#
|

# Many years ago Gwillim Law wrote that a good source
|

# published semiannually. Law sent in several helpful summaries
|

# of the IATA's data after 1990. Except where otherwise noted,
|
||
# IATA SSIM is the source for entries after 1990.
|
||
#
|
||
# A reliable and entertaining source about time zones is
|
||
# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
|

|
||
# Britain (United Kingdom) and Ireland (Eire)
|
||
|
||
# From Peter Ilieve (1994-07-06):
|
||
#
|
||
# On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about
|
||
# historical vistas along the Thames in west London. There was a photo
|
||
# and a sketch map showing some of the sightlines involved. One paragraph
|
||
# of the text said:
|
||
#
|
||
# 'An old stone obelisk marking a forgotten terrestrial meridian stands
|
||
# beside the river at Kew. In the 18th century, before time and longitude
|
||
# was standardised by the Royal Observatory in Greenwich, scholars observed
|
||
# this stone and the movement of stars from Kew Observatory nearby. They
|
||
# made their calculations and set the time for the Horse Guards and Parliament,
|
||
# but now the stone is obscured by scrubwood and can only be seen by walking
|
||
# along the towpath within a few yards of it.'
|
||
#
|
||
# I have a one inch to one mile map of London and my estimate of the stone's
|
||
# position is 51° 28' 30" N, 0° 18' 45" W. The longitude should
|
||
# be within about ±2". The Ordnance Survey grid reference is TQ172761.
|
||
#
|
||
# [This yields STDOFF = -0:01:15 for London LMT in the 18th century.]
|
||
|
||
# From Paul Eggert (1993-11-18):
|
||
#
|
||
# Howse writes that Britain was the first country to use standard time.
|
||
# The railways cared most about the inconsistencies of local mean time,
|
||
# and it was they who forced a uniform time on the country.
|
||
# The original idea was credited to Dr. William Hyde Wollaston (1766-1828)
|
||
# and was popularized by Abraham Follett Osler (1808-1903).
|
||
# The first railway to adopt London time was the Great Western Railway
|
||
# in November 1840; other railways followed suit, and by 1847 most
|
||
# (though not all) railways used London time. On 1847-09-22 the
|
||
# Railway Clearing House, an industry standards body, recommended that GMT be
|
||
# adopted at all stations as soon as the General Post Office permitted it.
|
||
# The transition occurred on 12-01 for the L&NW, the Caledonian,
|
||
# and presumably other railways; the January 1848 Bradshaw's lists many
|
||
# railways as using GMT. By 1855 the vast majority of public
|
||
# clocks in Britain were set to GMT (though some, like the great clock
|
||
# on Tom Tower at Christ Church, Oxford, were fitted with two minute hands,
|
||
# one for local time and one for GMT). The last major holdout was the legal
|
||
# system, which stubbornly stuck to local time for many years, leading
|
||
# to oddities like polls opening at 08:13 and closing at 16:13.
|
||
# The legal system finally switched to GMT when the Statutes (Definition
|
||
# of Time) Act took effect; it received the Royal Assent on 1880-08-02.
|
||
#
|
||
# In the tables below, we condense this complicated story into a single
|
||
# transition date for London, namely 1847-12-01. We don't know as much
|
||
# about Dublin, so we use 1880-08-02, the legal transition time.
|
||
|
||
# From Paul Eggert (2014-07-19):
|
||
# The ancients had no need for daylight saving, as they kept time
|
||
# informally or via hours whose length depended on the time of year.
|
||
# Daylight saving time in its modern sense was invented by the
|
||
# New Zealand entomologist George Vernon Hudson (1867-1946),
|
||
# whose day job as a postal clerk led him to value
|
||
# after-hours daylight in which to pursue his research.
|
||
# In 1895 he presented a paper to the Wellington Philosophical Society
|
||
# that proposed a two-hour daylight-saving shift. See:
|
||
# Hudson GV. On seasonal time-adjustment in countries south of lat. 30°.
|
||
# Transactions and Proceedings of the New Zealand Institute. 1895;28:734
|
||
# http://rsnz.natlib.govt.nz/volume/rsnz_28/rsnz_28_00_006110.html
|
||
# Although some interest was expressed in New Zealand, his proposal
|
||
# did not find its way into law and eventually it was almost forgotten.
|
||
#
|
||
# In England, DST was independently reinvented by William Willett (1857-1915),
|
||
# a London builder and member of the Royal Astronomical Society
|
||
# who circulated a pamphlet "The Waste of Daylight" (1907)
|
||
# that proposed advancing clocks 20 minutes on each of four Sundays in April,
|
||
# and retarding them by the same amount on four Sundays in September.
|
||
# A bill was drafted in 1909 and introduced in Parliament several times,
|
||
# but it met with ridicule and opposition, especially from farming interests.
|
||
# Later editions of the pamphlet proposed one-hour summer time, and
|
||
# it was eventually adopted as a wartime measure in 1916.
|
||
# See: Summer Time Arrives Early, The Times (2000-05-18).
|
||
# A monument to Willett was unveiled on 1927-05-21, in an open space in
|
||
# a 45-acre wood near Chislehurst, Kent that was purchased by popular
|
||
# subscription and open to the public. On the south face of the monolith,
|
||
# designed by G. W. Miller, is the William Willett Memorial Sundial,
|
||
# which is permanently set to Summer Time.
|
||
|
||
# From Winston Churchill (1934-04-28):
|
||
# It is one of the paradoxes of history that we should owe the boon of
|
||
# summer time, which gives every year to the people of this country
|
||
# between 160 and 170 hours more daylight leisure, to a war which
|
||
# plunged Europe into darkness for four years, and shook the
|
||
# foundations of civilization throughout the world.

|
||
|
||
# From Paul Eggert (2015-08-08):
|
||
# The OED Supplement says that the English originally said "Daylight Saving"
|
||
# when they were debating the adoption of DST in 1908; but by 1916 this
|
||
# term appears only in quotes taken from DST's opponents, whereas the
|
||
# proponents (who eventually won the argument) are quoted as using "Summer".
|
||
# The term "Summer Time" was introduced by Herbert Samuel, Home Secretary; see:
|
||
# Viscount Samuel. Leisure in a Democracy. Cambridge University Press
|
||
# ISBN 978-1-107-49471-8 (1949, reissued 2015), p 8.
|
||
|
||
# From Arthur David Olson (1989-01-19):
|
||
# A source at the British Information Office in New York avers that it's
|
||
# known as "British" Summer Time in all parts of the United Kingdom.
|
||
|
||
# Date: 4 Jan 89 08:57:25 GMT (Wed)
|
||
# From: Jonathan Leffler
|
||
# [British Summer Time] is fixed annually by Act of Parliament.
|
||
# If you can predict what Parliament will do, you should be in
|
||
# politics making a fortune, not computing.
|
||
|
||
# From Chris Carrier (1996-06-14):
|
||
# I remember reading in various wartime issues of the London Times the
|
||
# acronym BDST for British Double Summer Time. Look for the published
|
||
# time of sunrise and sunset in The Times, when BDST was in effect, and
|
||
# if you find a zone reference it will say, "All times B.D.S.T."
|
||
|
||
# From Joseph S. Myers (1999-09-02):
|
||
# ... some military cables (WO 219/4100 - this is a copy from the
|
||
# main SHAEF archives held in the US National Archives, SHAEF/5252/8/516)
|
||
# agree that the usage is BDST (this appears in a message dated 17 Feb 1945).
|
||
|
||
# From Joseph S. Myers (2000-10-03):
|
||
# On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir
|
||
# Alexander Maxwell of the Home Office asking whether there was any
|
||
# official designation; the reply of the 21st was that there wasn't
|
||
# but he couldn't think of anything better than the "Double British
|
||
# Summer Time" that the BBC had been using informally.

|
||
# https://www.polyomino.org.uk/british-time/ho-19410421.png
|
||
|
||
# From Sir Alexander Maxwell in the above-mentioned letter (1941-04-21):
|
||
# [N]o official designation has as far as I know been adopted for the time
|
||
# which is to be introduced in May....
|
||
# I cannot think of anything better than "Double British Summer Time"
|
||
# which could not be said to run counter to any official description.
|
||
|
||
# From Paul Eggert (2000-10-02):
|
||
# Howse writes (p 157) 'DBST' too, but 'BDST' seems to have been common
|
||
# and follows the more usual convention of putting the location name first,
|
||
# so we use 'BDST'.
|
||
|
||
# Peter Ilieve (1998-04-19) described at length
|
||
# the history of summer time legislation in the United Kingdom.
|
||
# Since 1998 Joseph S. Myers has been updating
|
||
# and extending this list, which can be found in
|
||
# https://www.polyomino.org.uk/british-time/
|
||
|
||
# From Joseph S. Myers (1998-01-06):
|
||
#
|
||
# The legal time in the UK outside of summer time is definitely GMT, not UTC;
|
||
# see Lord Tanlaw's speech
|
||
# https://www.publications.parliament.uk/pa/ld199798/ldhansrd/vo970611/text/70611-10.htm#70611-10_head0
|
||
# (Lords Hansard 11 June 1997 columns 964 to 976).
|
||
|
||
# From Paul Eggert (2006-03-22):
|
||
#
|
||
# For lack of other data, follow Shanks & Pottenger for Eire in 1940-1948.
|
||
#
|
||
# Given Ilieve and Myers's data, the following claims by Shanks & Pottenger
|
||
# are incorrect:
|
||
# * Wales did not switch from GMT to daylight saving time until
|
||
# 1921 Apr 3, when they began to conform with the rest of Great Britain.
|
||
# Actually, Wales was identical after 1880.
|
||
# * Eire had two transitions on 1916 Oct 1.
|
||
# It actually just had one transition.
|
||
# * Northern Ireland used single daylight saving time throughout WW II.
|
||
# Actually, it conformed to Britain.
|
||
# * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
|
||
# Actually, that date saw the usual switch to summer time.
|
||
# Standard time was not changed until 1968-10-27 (the clocks didn't change).
|
||
#
|
||
# Here is another incorrect claim by Shanks & Pottenger:
|
||
# * Jersey, Guernsey, and the Isle of Man did not switch from GMT
|
||
# to daylight saving time until 1921 Apr 3, when they began to
|
||
# conform with Great Britain.
|
||
# S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
|
||
#
|
||
# The following claim by Shanks & Pottenger is possible though doubtful;
|
||
# we'll ignore it for now.
|
||
# * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
|
||
|
||
# From Paul Eggert (2017-12-04):
|
||
#
|
||
# Dunsink Observatory (8 km NW of Dublin's center) was to Dublin as
|
||
# Greenwich was to London. For example:
|
||
#
|
||
# "Timeball on the ballast office is down. Dunsink time."
|
||
# -- James Joyce, Ulysses
|
||
#
|
||
# The abbreviation DMT stood for "Dublin Mean Time" or "Dunsink Mean Time";
|
||
# this being Ireland, opinions differed.
|
||
#
|
||
# Whitman says Dublin/Dunsink Mean Time was UT-00:25:21, which agrees
|
||
# with measurements of recent visitors to the Meridian Room of Dunsink
|
||
# Observatory; see Malone D. Dunsink and timekeeping. 2016-01-24.
|
||
# <https://www.maths.tcd.ie/~dwmalone/time/dunsink.html>. Malone
|
||
# writes that the Nautical Almanac listed UT-00:25:22 until 1896, when
|
||
# it moved to UT-00:25:21.1 (I confirmed that the 1893 edition used
|
||
# the former and the 1896 edition used the latter). Evidently the
|
||
# news of this change propagated slowly, as Milne 1899 still lists
|
||
# UT-00:25:22 and cites the International Telegraph Bureau. As it is
|
||
# not clear that there was any practical significance to the change
|
||
# from UT-00:25:22 to UT-00:25:21.1 in civil timekeeping, omit this
|
||
# transition for now and just use the latter value.
|
||
|
||
# "Countess Markievicz ... claimed that the [1916] abolition of Dublin Mean Time
|
||
# was among various actions undertaken by the 'English' government that
|
||
# would 'put the whole country into the SF (Sinn Féin) camp'. She claimed
|
||
# Irish 'public feeling (was) outraged by forcing of English time on us'."

# If, say, the British police were called to the station for some reason,
|
||
# I would expect the official police report to use GMT/BST and not CET/CEST.
|
||
# This is a borderline case, but for now let's stick to GMT/BST.
|
||
|
||
# From an anonymous contributor (1996-06-02):
|
||
# The law governing time in Ireland is under Statutory Instrument SI 395/94,
|
||
# which gives force to European Union 7th Council Directive No. 94/21/EC.
|
||
# Under this directive, the Minister for Justice in Ireland makes appropriate
|
||
# regulations. I spoke this morning with the Secretary of the Department of
|
||
# Justice (tel +353 1 678 9711) who confirmed to me that the correct name is
|
||
# "Irish Summer Time", abbreviated to "IST".
|
||
#
|
||
# From Paul Eggert (2017-12-07):
|
||
# The 1996 anonymous contributor's goal was to determine the correct
|
||
# abbreviation for summer time in Dublin and so the contributor
|
||
# focused on the "IST", not on the "Irish Summer Time". Though the
|
||
# "IST" was correct, the "Irish Summer Time" appears to have been an
|
||
# error, as Ireland's Standard Time (Amendment) Act, 1971 states that
|
||
# standard time in Ireland remains at UT +01 and is observed in
|
||
# summer, and that Greenwich mean time is observed in winter. (Thanks
|
||
# to Derick Rethans for pointing out the error.) That is, when
|
||
# Ireland amended the 1968 act that established UT +01 as Irish
|
||
# Standard Time, it left standard time unchanged and established GMT
|
||
# as a negative daylight saving time in winter. So, in this database
|
||
# IST stands for Irish Summer Time for timestamps before 1968, and for
|
||
# Irish Standard Time after that. See:

# From Paul Eggert (2018-02-15):
|

# In January 2018 we discovered that the negative SAVE values in the

# Eire rules cause problems with tests for ICU:
|
||
# https://mm.icann.org/pipermail/tz/2018-January/025825.html

# and with tests for OpenJDK:
|
||
# https://mm.icann.org/pipermail/tz/2018-January/025822.html
|
||
#
|
||
# To work around this problem, the build procedure can translate the
|
||
# following data into two forms, one with negative SAVE values and the
|
||
# other form with a traditional approximation for Irish timestamps
|
||
# after 1971-10-31 02:00 UTC; although this approximation has tm_isdst
|
||
# flags that are reversed, its UTC offsets are correct and this often
|
||
# suffices....
|
||
#
|
||
# The following is like GB-Eire and EU, except with standard time in
|
||
# summer and negative daylight saving time in winter. It is for when
|

# negative SAVE values are used.

|
||
# This quote helps explain the late-1914 situation:
|
||
# In early November 1914, the Germans imposed the time zone used in central
|
||
# Europe and forced the inhabitants to set their watches and public clocks
|
||
# sixty minutes ahead. Many were reluctant to accept "German time" and
|
||
# continued to use "Belgian time" among themselves. Reflecting the spirit of
|
||
# resistance that arose in the population, a song made fun of this change....
|
||
# The song ended:
|
||
# Putting your clock forward
|
||
# Will but hasten the happy hour
|
||
# When we kick out the Boches!

# (This is an official link to the Czechoslovak Summer Time Act of

# From Paul Eggert (2004-10-31):
|
||
# During World War II, Germany maintained secret manned weather stations in
|
||
# East Greenland and Franz Josef Land, but we don't know their time zones.
|
||
# My source for this is Wilhelm Dege's book mentioned under Svalbard.
|
||
#
|
||
# From Paul Eggert (2017-12-10):
|
||
# Greenland joined the European Communities as part of Denmark,
|
||
# obtained home rule on 1979-05-01, and left the European Communities
|
||
# on 1985-02-01. It therefore should have been using EU
|
||
# rules at least through 1984. Shanks & Pottenger say Scoresbysund and Godthåb
|
||
# used C-Eur rules after 1980, but IATA SSIM (1991/1996) says they use EU
|
||
# rules since at least 1991. Assume EU rules since 1980.
|
||
|
||
# From Gwillim Law (2001-06-06), citing
|
||
# <http://www.statkart.no/efs/efshefter/2001/efs5-2001.pdf> (2001-03-15),
|
||
# and with translations corrected by Steffen Thorsen:
|
||
#
|
||
# Greenland has four local times, and the relation to UTC
|
||
# is according to the following time line:
|
||
#
|
||
# The military zone near Thule UTC-4
|
||
# Standard Greenland time UTC-3
|
||
# Scoresbysund UTC-1
|
||
# Danmarkshavn UTC
|
||
#
|
||
# In the military area near Thule and in Danmarkshavn DST will not be
|
||
# introduced.
|
||
|
||
# From Rives McDow (2001-11-01):
|
||
#
|
||
# I correspond regularly with the Dansk Polarcenter, and wrote them at
|
||
# the time to clarify the situation in Thule. Unfortunately, I have
|
||
# not heard back from them regarding my recent letter. [But I have
|
||
# info from earlier correspondence.]
|
||
#
|
||
# According to the center, a very small local time zone around Thule
|
||
# Air Base keeps the time according to UTC-4, implementing daylight
|
||
# savings using North America rules, changing the time at 02:00 local time....
|
||
#
|
||
# The east coast of Greenland north of the community of Scoresbysund
|
||
# uses UTC in the same way as in Iceland, year round, with no dst.
|
||
# There are just a few stations on this coast, including the
|
||
# Danmarkshavn ICAO weather station mentioned in your September 29th
|
||
# email. The other stations are two sledge patrol stations in
|
||
# Mestersvig and Daneborg, the air force base at Station Nord, and the
|
||
# DPC research station at Zackenberg.
|
||
#
|
||
# Scoresbysund and two small villages nearby keep time UTC-1 and use
|
||
# the same daylight savings time period as in West Greenland (Godthåb).
|
||
#
|
||
# The rest of Greenland, including Godthåb (this area, although it
|
||
# includes central Greenland, is known as west Greenland), keeps time
|
||
# UTC-3, with daylight savings methods according to European rules.
|
||
#
|
||
# It is common procedure to use UTC 0 in the wilderness of East and
|
||
# North Greenland, because it is mainly Icelandic aircraft operators
|
||
# maintaining traffic in these areas. However, the official status of
|
||
# this area is that it sticks with Godthåb time. This area might be
|
||
# considered a dual time zone in some respects because of this.
|
||
|
||
# From Rives McDow (2001-11-19):
|
||
# I heard back from someone stationed at Thule; the time change took place
|
||
# there at 2:00 AM.
|
||
|
||
# From Paul Eggert (2006-03-22):
|
||
# From 1997 on the CIA map shows Danmarkshavn on GMT;
|
||
# the 1995 map as like Godthåb.
|
||
# For lack of better info, assume they were like Godthåb before 1996.
|
||
# startkart.no says Thule does not observe DST, but this is clearly an error,
|
||
# so go with Shanks & Pottenger for Thule transitions until this year.
|
||
# For 2007 on assume Thule will stay in sync with US DST rules.
|
||
|
||
# From J William Piggott (2016-02-20):

|

#
|
||
# From Thomas M. Steenholdt (2022-12-02):
|
||
# - The bill to move America/Nuuk from UTC-03 to UTC-02 passed.
|
||
# - The bill to stop observing DST did not (Greenland will stop observing DST
|
||
# when EU does).
|
||
# Details on the implementation are here (section 6):
|
||
# https://ina.gl/dvd/EM%202022/pdf/media/2553529/pkt17_em2022_tidens_bestemmelse_bem_da.pdf
|
||
# This is how the change will be implemented:
|
||
# 1. The shift *to* DST in 2023 happens as normal.
|
||
# 2. The shift *from* DST in 2023 happens as normal, but coincides with the
|
||
# shift to UTC-02 normaltime (people will not change their clocks here).
|
||
# 3. After this, DST is still observed, but as -02/-01 instead of -03/-02.
|
||
#
|
||
# From Múte Bourup Egede via Jógvan Svabo Samuelsen (2023-03-15):
|
||
# Greenland will not switch to Daylight Saving Time this year, 2023,
|
||
# because the standard time for Greenland will change from UTC -3 to UTC -2.
|
||
# However, Greenland will change to Daylight Saving Time again in 2024

# and onwards.

# From Peter Ilieve (1994-10-15):

# a regulation of the Government of Estonia, No. 111 of 1989....
|
||
#
|
||
# From Peter Ilieve (1996-10-28):
|
||
# [IATA SSIM (1992/1996) claims that the Baltic republics switch at 01:00s,

# From Janne Snabb (2010-07-15):

|

# There are also precise reports about how the change was prepared in train

# (or were covered), only the chief of service had a watch, labeled

|
||
# From Michael Deckers (2020-06-12):
|
||
# That "all French clocks stopped" for 00:09:21 is a misreading of French
|
||
# newspapers; this sort of adjustment applies only to certain
|
||
# remote-controlled clocks ("pendules pneumatiques", of which there existed
|
||
# perhaps a dozen in Paris, and which simply could not be set back remotely),
|
||
# but not to all the clocks in all French towns and villages. For instance,
|
||
# the following story in the "Courrier de Saône-et-Loire" 1911-03-11, page 2:
|
||
# only works if legal time was stepped back (was not monotone): ...
|
||
# [One can observe that children who had been born at midnight less 5
|
||
# minutes and who had died at midnight of the old time, would turn out to
|
||
# be dead before being born, time having been set back and having
|
||
# suppressed 9 minutes and 25 seconds of their existence, that is, more
|
||
# than they could spend.]
|
||
#
|
||
# From Paul Eggert (2020-06-12):
|
||
# French time in railway stations was legally five minutes behind civil time,
|
||
# which explains why railway "old time" ran to 00:04:21 instead of to 00:09:21.
|
||
# The law's text (which Michael Deckers noted is at
|
||
# <https://gallica.bnf.fr/ark:/12148/bpt6k2022333z/f2>) says only that
|
||
# at 1911-03-11 00:00 legal time was that of Paris mean time delayed by
|
||
# nine minutes and twenty-one seconds, and does not say how the
|
||
# transition from Paris mean time was to occur.
|
||
#
|
||
# tzdb has no way to represent stopped clocks. As the railway practice
|
||
# was to keep a watch running on "old time" to decide when to restart
|
||
# the other clocks, this could be modeled as a transition for "old time" at
|
||
# 00:09:21. However, since the law was ambiguous and clocks outside railway
|
||
# stations were probably done haphazardly with the popular impression being
|
||
# that the transition was done at 00:00 "old time", simply leave the time
|
||
# blank; this causes zic to default to 00:00 "old time" which is good enough.
|
||
# Do something similar for the 1891-03-16 transition. There are similar
|
||
# problems in Algiers, Monaco and Tunis.
|
||
|
||
#
|
||
# Shank & Pottenger seem to use '24:00' ambiguously; resolve it with Whitman.

# Svalbard & Jan Mayen
|
||
|
||
# From Steffen Thorsen (2001-05-01):
|
||
# Although I could not find it explicitly, it seems that Jan Mayen and
|
||
# Svalbard have been using the same time as Norway at least since the
|
||
# time they were declared as parts of Norway. Svalbard was declared
|
||
# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
|
||
# Mayen by law of 1930-02-27 no 2, section 2. (From
|
||
# <http://www.lovdata.no/all/nl-19250717-011.html> and
|
||
# <http://www.lovdata.no/all/nl-19300227-002.html>). The law/regulation
|
||
# for normal/standard time in Norway is from 1894-06-29 no 1 (came
|
||
# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
|
||
# part of this law since 1925/1930. (From
|
||
# <http://www.lovdata.no/all/nl-18940629-001.html>) I have not been
|
||
# able to find if Jan Mayen used a different time zone (e.g. -0100)
|
||
# before 1930. Jan Mayen has only been "inhabited" since 1921 by
|
||
# Norwegian meteorologists and maybe used the same time as Norway ever
|
||
# since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since
|
||
# before 1895, and therefore probably changed the local time somewhere
|
||
# between 1895 and 1925 (inclusive).
|
||
|
||
# From Paul Eggert (2013-09-04):
|
||
#
|
||
# Actually, Jan Mayen was never occupied by Germany during World War II,
|
||
# so it must have diverged from Oslo time during the war, as Oslo was
|
||
# keeping Berlin time.
|
||
#
|
||
# <https://www.jan-mayen.no/history.htm> says that the meteorologists
|
||
# burned down their station in 1940 and left the island, but returned in
|
||
# 1941 with a small Norwegian garrison and continued operations despite
|
||
# frequent air attacks from Germans. In 1943 the Americans established a
|
||
# radiolocating station on the island, called "Atlantic City". Possibly
|
||
# the UT offset changed during the war, but I think it unlikely that
|
||
# Jan Mayen used German daylight-saving rules.
|
||
#
|
||
# Svalbard is more complicated, as it was raided in August 1941 by an
|
||
# Allied party that evacuated the civilian population to England (says
|
||
# <http://www.bartleby.com/65/sv/Svalbard.html>). The Svalbard FAQ
|
||
# <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were
|
||
# expelled on 1942-05-14. However, small parties of Germans did return,
|
||
# and according to Wilhelm Dege's book "War North of 80" (1954)
|
||
# http://www.ucalgary.ca/UofC/departments/UP/1-55238/1-55238-110-2.html
|
||
# the German armed forces at the Svalbard weather station code-named
|
||
# Haudegen did not surrender to the Allies until September 1945.

#
|

# From Paul Eggert (2001-03-06):
|
||
# Sicily and Sardinia each had their own time zones from 1866 to 1893,
|
||
# called Palermo Time (+00:53:28) and Cagliari Time (+00:36:32).
|
||
# During World War II, German-controlled Italy used German time.
|
||
# But these events all occurred before the 1970 cutoff,
|
||
# so record only the time in Rome.
|
||
#
|
||
# From Stephen Trainor (2019-05-06):
|
||
# http://www.ac-ilsestante.it/MERIDIANE/ora_legale/ORA_LEGALE_ESTIVA_IN_ITALIA.htm
|
||
# ... the [1866] law went into effect on 12 December 1866, rather than
|
||
# the date of the decree (22 Sep 1866)
|
||
# https://web.archive.org/web/20070824155341/http://www.iav.it/planetario/didastro/didastro/english.htm
|
||
# ... "In Italy in 1866 there were 6 railway times (Torino, Verona, Firenze,
|
||
# Roma, Napoli, Palermo). On that year it was decided to unify them, adopting
|
||
# the average time of Rome (even if this city was not yet part of the
|
||
# kingdom). On the 12th December 1866, on the starting of the winter time
|
||
# table, it took effect in the railways, the post office and the telegraph,
|
||
# not only for the internal service but also for the public.... Milano set
|
||
# the public watches on the Rome time on the same day (12th December 1866),
|
||
# Torino and Bologna on the 1st January 1867, Venezia the 1st May 1880 and the
|
||
# last city was Cagliari in 1886."

|
||
#
|
||
# From Michael Deckers (2016-10-24):
|
||
# http://www.ac-ilsestante.it/MERIDIANE/ora_legale quotes a law of 1893-08-10
|
||
# ... [translated as] "The preceding dispositions will enter into
|
||
# force at the instant at which, according to the time specified in
|
||
# the 1st article, the 1st of November 1893 will begin...."
|
||
#
|
||
# From Pierpaolo Bernardi (2016-10-20):
|
||
# The authoritative source for time in Italy is the national metrological
|
||
# institute, which has a summary page of historical DST data at
|
||
# http://www.inrim.it/res/tf/ora_legale_i.shtml
|
||
# [now at http://oldsite.inrim.it/res/tf/ora_legale_i.shtml as of 2017]
|
||
# (2016-10-24):
|
||
# http://www.renzobaldini.it/le-ore-legali-in-italia/
|
||
# has still different data for 1944. It divides Italy in two, as
|
||
# there were effectively two governments at the time, north of Gothic
|
||
# Line German controlled territory, official government RSI, and south
|
||
# of the Gothic Line, controlled by allied armies.
|
||
#
|
||
# From Brian Inglis (2016-10-23):
|
||
# Viceregal LEGISLATIVE DECREE. 14 September 1944, no. 219.
|
||
# Restoration of Standard Time. (044U0219) (OJ 62 of 30.9.1944) ...
|
||
# Given the R. law decreed on 1944-03-29, no. 92, by which standard time is
|
||
# advanced to sixty minutes later starting at hour two on 1944-04-02; ...
|
||
# Starting at hour three on the date 1944-09-17 standard time will be resumed.
|
||
#
|
||
# From Alois Treindl (2019-07-02):
|
||
# I spent 6 Euros to buy two archive copies of Il Messaggero, a Roman paper,
|
||
# for 1 and 2 April 1944. The edition of 2 April has this note: "Tonight at 2
|
||
# am, put forward the clock by one hour. Remember that in the night between
|
||
# today and Monday the 'ora legale' will come in force again." That makes it
|
||
# clear that in Rome the change was on Monday, 3 April 1944 at 2 am.
|
||
#
|
||
# From Paul Eggert (2021-10-05):
|
||
# Go with INRiM for DST rules, except as corrected by Inglis for 1944
|
||
# for the Kingdom of Italy. This is consistent with Renzo Baldini.
|
||
# Model Rome's occupation by using C-Eur rules from 1943-09-10
|
||
# to 1944-06-04; although Rome was an open city during this period, it
|
||
# was effectively controlled by Germany. Using C-Eur is consistent
|
||
# with Treindl's comment about Rome in April 1944, as the "Rule Italy"
|
||
# lines during German occupation do not affect Europe/Rome
|
||
# (though they do affect Europe/Malta).

# ... says that since 1990-05-06 on the territory of the Moldavian SSR
|
||
# time would be calculated as the standard time of the second time belt
|
||
# plus one hour of the "summer" time. To implement that clocks would be
|
||
# adjusted one hour backwards at 1990-05-06 2:00. After that "summer"
|
||
# time would be cancelled last Sunday of September at 3:00 and
|
||
# reintroduced last Sunday of March at 2:00.
|
||
|
||
# From Paul Eggert (2006-03-22):
|
||
# A previous version of this database followed Shanks & Pottenger, who write
|
||
# that Tiraspol switched to Moscow time on 1992-01-19 at 02:00.
|
||
# However, this is most likely an error, as Moldova declared independence
|
||
# on 1991-08-27 (the 1992-01-19 date is that of a Russian decree).
|
||
# In early 1992 there was large-scale interethnic violence in the area
|
||
# and it's possible that some Russophones continued to observe Moscow time.
|
||
# But [two people] separately reported via
|
||
# Jesper Nørgaard that as of 2001-01-24 Tiraspol was like Chisinau.
|
||
# The Tiraspol entry has therefore been removed for now.
|
||
#
|
||
# From Alexander Krivenyshev (2011-10-17):
|
||
# Pridnestrovian Moldavian Republic (PMR, also known as
|
||
# "Pridnestrovie") has abolished seasonal clock change (no transition
|
||
# to the Winter Time).

# The substance of this change (reinstatement of the Tiraspol entry)
|

# is from a patch from Petr Machata (2011-10-17)
|
||
#
|
||
# From Tim Parenti (2011-10-19)
|
||
# In addition, being situated at +4651+2938 would give Tiraspol
|
||
# a pre-1880 LMT offset of 1:58:32.
|
||
#
|
||
# (which agrees with the earlier entry that had been removed)
|
||
#
|
||
# From Alexander Krivenyshev (2011-10-26)
|
||
# NO need to divide Moldova into two timezones at this point.
|
||
# As of today, Transnistria (Pridnestrovie)- Tiraspol reversed its own
|
||
# decision to abolish DST this winter.
|
||
# Following Moldova and neighboring Ukraine- Transnistria (Pridnestrovie)-
|

# Tiraspol will go back to winter time on October 30, 2011.

#

# From Michael Deckers (2018-02-15):
|
||
# article 5 [of the 1911 decree; Deckers's translation] ...:
|
||
# These dispositions shall enter into force at the instant at which,

||
# according to the 2nd article, the civil day January 1, 1912 begins,

||
# all clocks therefore having to be advanced or set back correspondingly ...
|

|

# From Rui Pedro Salgueiro (1992-11-12):

# Portugal has recently (September, 27) changed timezone

# (from WET to MET or CET) to harmonize with EEC.
|

#
|

# Martin Bruckmann (1996-02-29) reports via Peter Ilieve

# There's considerable evidence that Sakhalin Island used to be in

# as the South and Middle Kurils have been on UTC+11 (SAKT) with the rest of

#
|
||
# In the 1918 and 1919 fallback transitions in Spain, the clock for

# the hour-longer day officially kept going after midnight, so that

# with a fallback transition from the second occurrence of 00:59... to

# From Alois Treindl (2008-12-17):
|
||
# I have researched the DST usage in Switzerland during the 1940ies.
|
||
#
|
||
# As I wrote in an earlier message, I suspected the current tzdata values
|
||
# to be wrong. This is now verified.
|
||
#
|
||
# I have found copies of the original ruling by the Swiss Federal
|
||
# government, in 'Eidgenössische Gesetzessammlung 1941 and 1942' (Swiss
|
||
# federal law collection)...
|
||
#
|
||
# DST began on Monday 5 May 1941, 1:00 am by shifting the clocks to 2:00 am
|
||
# DST ended on Monday 6 Oct 1941, 2:00 am by shifting the clocks to 1:00 am.
|

#
|
||
# DST began on Monday, 4 May 1942 at 01:00 am
|
||
# DST ended on Monday, 5 Oct 1942 at 02:00 am
|
||
#
|
||
# There was no DST in 1940, I have checked the law collection carefully.
|
||
# It is also indicated by the fact that the 1942 entry in the law
|
||
# collection points back to 1941 as a reference, but no reference to any
|
||
# other years are made.
|
||
#
|
||
# Newspaper articles I have read in the archives on 6 May 1941 reported
|
||
# about the introduction of DST (Sommerzeit in German) during the previous
|
||
# night as an absolute novelty, because this was the first time that such
|
||
# a thing had happened in Switzerland.
|
||
#
|
||
# I have also checked 1916, because one book source (Gabriel, Traité de
|
||
# l'heure dans le monde) claims that Switzerland had DST in 1916. This is
|
||
# false, no official document could be found. Probably Gabriel got misled
|
||
# by references to Germany, which introduced DST in 1916 for the first time.
|
||
#
|
||
# The tzdata rules for Switzerland must be changed to:
|
||
# Rule Swiss 1941 1942 - May Mon>=1 1:00 1:00 S
|
||
# Rule Swiss 1941 1942 - Oct Mon>=1 2:00 0 -
|

#
|
||
# The 1940 rules must be deleted.
|
||
#
|
||
# One further detail for Switzerland, which is probably out of scope for
|
||
# most users of tzdata: The [Europe/Zurich zone] ...
|
||
# describes all of Switzerland correctly, with the exception of
|
||
# the Canton de Genève (Geneva, Genf). Between 1848 and 1894 Geneva did not
|
||
# follow Bern Mean Time but kept its own local mean time.
|
||
# To represent this, an extra zone would be needed.
|
||
#
|
||
# From Alois Treindl (2013-09-11):

|
||
# http://www.amtsdruckschriften.bar.admin.ch/viewOrigDoc.do?id=10071353

# ISBN 3-905311-68-2, OCLC 717570797.
|
||
#
|
||
# suggests that the transition was more gradual, and that the Swiss did not
|
||
# agree about civil time during the transition. The timekeeping it gives the
|
||
# most detail for is postal and telegraph time: here, federal legislation (the
|
||
# "Bundesgesetz über die Erstellung von elektrischen Telegraphen") passed on
|
||
# 1851-11-23, and an official implementation notice was published 1853-07-16
|
||
# (Bundesblatt 1853, Bd. II, S. 859). On p 72 Messerli writes that in
|
||
# practice since July 1853 Bernese time was used in "all postal and telegraph
|
||
# offices in Switzerland from Geneva to St. Gallen and Basel to Chiasso"
|
||
# (Google translation). For now, model this transition as occurring on
|
||
# 1853-07-16, though it probably occurred at some other date in Zurich, and
|
||
# legal civil time probably changed at still some other transition date.

# This decision changes the default longitude for Turkish time zone from 30
|
||
# degrees East to 45 degrees East. This means a standard TZ change, from +2
|
||
# to +3. This is published & applied on 1978-06-29. At that time, Turkey was
|
||
# already on summer time (already on 45E). Hence, this new law just meant an
|
||
# "continuous summer time". Note that this was reversed in a few years.

# 1984. This decision is published on 10/31/1984. Page 1 declares
|

# the decision of reverting the "default longitude change". So the

# standard time should go back to +3 (30E). And page 34 explains when
|

# that will happen: 1984-11-01 02:00 -> 01:00. You can think of this

|
||
# REGULATION A N O V A on March 20, 1992 N 139 ... means that from
|

||
# CABINET OF MINISTERS OF UKRAINE RESOLUTION on May 13, 1996 N 509
|
||
# "On the order of computation time on the territory of Ukraine" ....
|
||
# As this cabinet decision is from May 1996, it seems likely that the
|
||
# transition in March 1996, which predates it, was still at 2:00 am
|
||
# and not at 3:00 as would have been under EU rules.
|
||
# This is why I have set the change to EU rules into May 1996,
|
||
# so that the change in March is stil covered by the Ukraine rule.
|
||
# The next change in October 1996 happened under EU rules.
|
||
#
|
||
# From Paul Eggert (2022-08-27):
|
||
# For now, assume that Ukraine's zones all followed the same rules,

# except that Crimea switched to Moscow time in 1994 as described elsewhere.

||
# From Igor Karpov, who works for the Ukrainian Ministry of Justice,
|

# via Garrett Wollman (2003-01-27):

# BTW, I've found the official document on this matter. It's government

||
# of March at 3am the time is changing to 4am and each last Sunday of
|
||
# October the time at 4am is changing to 3am"

# From Alexander Krivenyshev (2011-09-20):

||
# first Sunday in April and last Sunday in September...
|
||
# In 1981 UK joined Europe insofar that
|
||
# the starting day for both shifted to last Sunday in March. And from 1982
|
||
# the whole of Europe used DST, with switch dates April 1 and October 1 in
|
||
# the Sov[i]et Union. In 1985 the SU reverted to standard Europe[a]n switch
|
||
# dates...
|
||
#
|
||
# It should also be remembered that time-zones are not constants; e.g.
|
||
# Portugal switched in 1976 from MET (or CET) to WET with DST...
|
||
# Note also that though there were rules for switch dates not
|
||
# all countries abided to these dates, and many individual deviations
|
||
# occurred, though not since 1982 I believe. Another note: it is always
|
||
# assumed that DST is 1 hour ahead of normal time, this need not be the
|
||
# case; at least in the Netherlands there have been times when DST was 2 hours
|
||
# in advance of normal time.
