65# INFORMATION ON UTC - TAI
66#
67# NO positive leap second will be introduced at the end of December 2001.
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.
