0N/A# Allowance for leapseconds added to each timezone file.
0N/A# The International Earth Rotation Service periodically uses leap seconds
0N/A# to keep UTC to within 0.9 s of UT1
0N/A# (which measures the true angular orientation of the earth in space); see
0N/A# Terry J Quinn, The BIPM and the accurate measure of time,
0N/A# Proc IEEE 79, 7 (July 1991), 894-905.
0N/A# There were no leap seconds before 1972, because the official mechanism
0N/A# accounting for the discrepancy between atomic time and the earth's rotation
0N/A# did not exist until the early 1970s.
0N/A# The correction (+ or -) is made at the given time, so lines
0N/A# will typically look like:
0N/A# Leap YEAR MON DAY 23:59:60 + R/S
0N/A# Leap YEAR MON DAY 23:59:59 - R/S
0N/A# If the leapsecond is Rolling (R) the given time is local time
0N/A# If the leapsecond is Stationary (S) the given time is UTC
0N/A# Leap YEAR MONTH DAY HH:MM:SS CORR R/S

# To authorities responsible
# for the measurement and
# on the 1st of January 2009
# A positive leap second will be introduced at the end of December 2008.
# The sequence of dates of the UTC second markers will be:
# 2008 December 31, 23h 59m 59s
# 2008 December 31, 23h 59m 60s
# 2009 January 1, 0h 0m 0s
# The difference between UTC and the International Atomic Time TAI is:
# from 2006 January 1, 0h UTC, to 2009 January 1 0h UTC : UTC-TAI = - 33s
# from 2009 January 1, 0h UTC, until further notice : UTC-TAI = - 34s
# 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.
