-# 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
