                                              Bulletin C 36

                                              To authorities responsible
					      for the measurement and
					      distribution of time


                                   UTC TIME STEP
                            on the 1st of January 2009


 A positive leap second will be introduced at the end of December 2008.
 The sequence of dates of the UTC second markers will be:

                          2008 December 31,     23h 59m 59s
                          2008 December 31,     23h 59m 60s
                          2009 January   1,      0h  0m  0s

 The difference between UTC and the International Atomic Time TAI is:

  from 2006 January 1, 0h UTC, to 2009 January 1  0h UTC  : UTC-TAI = - 33s
  from 2009 January 1, 0h UTC, until further notice       : 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
 will be no time step at the next possible date.

Oooh!  Today's my birthday.  What a lovely gift!  Just what I wanted -  
one size fits all!

(Though I bet some of you are thinking, "You really shouldn't have!" :-)

And Poul-Henning and I owe each other a beer, should we ever find  
ourselves in the same locale :-)  (I'll be in Portland, OR next week,  
Santa Barbara at the beginning of August, Baltimore in October, Qu?bec  
in November.)

As opposed to those ill-fitting rubber seconds that bound and pinched in all 
the wrong places...

What a coincidence... I was born on the fourth of July too!  (I was 
away at a convention and am just catching up on my mail.)
