Neujahr 2009. Bitte nicht zu früh feiern!

Wenn man sich mit NTP beschäftigt, stolpert man zwangsläufig auch über solche Spezialitäten wie Schaltsekunden. Original von hier . Wen’s genau interessiert: Leap_Second.txt.

                                              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.
