Here's the most recent one, downloaded from the IERS Web site:

                                                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.
