65# INFORMATION ON UTC - TAI |
66# |
67# NO positive leap second will be introduced at the end of June 2002. 68# The difference between UTC and the International Atomic Time TAI is : 69# 70# from 1999 January 1, 0h UTC, until further notice : UTC-TAI = -32 s |
71# |
72# Leap seconds can be introduced in UTC at the end of the months of December 73# or June, depending on the evolution of UT1-TAI. Bulletin C is mailed every 74# six months, either to announce a time step in UTC, or to confirm that there 75# will be no time step at the next possible date. |
