                                              To authorities responsible
                                              for the measurement and

                          INFORMATION ON UTC - TAI


 NO leap second will be introduced at the end of December 2021.
 The difference between Coordinated Universal Time UTC and the
 International Atomic Time TAI is :

     from 2017 January 1, 0h UTC, until further notice : UTC-TAI = -37 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.
