-# 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

-# 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.
