-# 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.
