Bulletin C 32
To authorities
esponsible
for the measurement and
distribution of time
INFORMATION ON UTC - TAI
NO positive leap second will be introduced at the end of December 2006.
The difference between Coordinated Universal Time UTC and the
International Atomic Time TAI is :
from 2006 January 1, 0h UTC, until further notice : UTC-TAI = -33 s
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.
