# 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 UT1
|
|
# (which measures the true angular orientation of the earth in space); 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

|
|
# A positive leap second will be introduced at the end of June 2012.
|
|
# The sequence of dates of the UTC second markers will be:
|
|
#
|
|
# 2012 June 30, 23h 59m 59s
|
|
# 2012 June 30, 23h 59m 60s
|
|
# 2012 July 1, 0h 0m 0s
|
|
#
|
|
# The difference between UTC and the International Atomic Time TAI is:
|
|
#
|
|
# from 2009 January 1, 0h UTC, to 2012 July 1 0h UTC : UTC-TAI = - 34s
|
|
# from 2012 July 1, 0h UTC, until further notice : UTC-TAI = - 35s
|
|
#
|
|
# Leap seconds can be introduced in UTC at the end of the months of December
|
|
# or June, depending on the evolution of UT1-TAI. Bulletin C is mailed every
|
|
# six months, either to announce a time step in UTC or to confirm that there
|
|
# will be no time step at the next possible date.
