# @(#)leapseconds 7.11
|
|
|
|
# Allowance for leapseconds added to each timezone file.
|
|
|
|
# The International Earth Rotation Service periodically uses leap seconds
|
|
# to keep UTC to within 0.9 s of TAI (atomic time); see
|
|
# Terry J Quinn, The BIPM and the accurate measure of time,
|
|
# Proc IEEE 79, 7 (July 1991), 894-905.
|
|
# There were no leap seconds before 1972, because the official mechanism
|
|
# accounting for the discrepancy between atomic time and the earth's rotation
|
|
# did not exist until the early 1970s.
|
|
|
|
# The correction (+ or -) is made at the given time, so lines
|
|
# will typically look like:
|
|
# Leap YEAR MON DAY 23:59:60 + R/S
|
|
# or
|
|
# Leap YEAR MON DAY 23:59:59 - R/S
|
|
|
|
# If the leapsecond is Rolling (R) the given time is local time
|
|
# If the leapsecond is Stationary (S) the given time is UTC
|
|
|
|
# Leap YEAR MONTH DAY HH:MM:SS CORR R/S
