P.S. У меня одна программа при запуске предупреждает об отсутствии файла
/usr/local/lib/leapseconds. Судя по всему, файл должен быть вида:
# @(#)leapseconds 7.12
# 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

Хочется найти с текущим годом и на некоторую перспективу. Я поискал, но
пока не нашёл.
