# 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

|

# 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
