Updated leapsecs.dat

[Alex Pennace]

The International Earth Rotation Service has scheduled the next leap
second for December 31, 2008. Attached is the announcement and an
updated leapsecs.dat.

Here is how I generated the new leapsecs.dat, using
http://cr.yp.to/libtai/libtai-0.60.tar.gz:

echo [phone] >> leapsecs.txt
echo [phone] >> leapsecs.txt
make leapsecs
./leapsecs < leapsecs.txt > leapsecs.dat

                                              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.

Another option would be to use my leapsunpack package:

<URL:http://su.bze.ro/software/leapsunpack-0.05.tar.gz>

I wrote it during the long and unprecedented gap in new leapseconds,
so I'm not entirely sure it was useful until recently.
