As you are probably aware, international discussions are in progress on a
redefinition of UTC, including a possible suppression of the leap seconds
To reply to the request of several international organizations on a possible
evolution of UTC the International Telecommunication Union, ITU decided in
October 2000 the creation of a Working Group called "Special Rapporteur
Group", SRG chaired by Mr Ron Beard of the Naval Research Laboratory (NRL-
USA), in charge of studying by a large consultation the different possible
solutions. The SRG reports its conclusions to the ITU working party WP-7A.
The Special Rapporteur Group (SRG) organized a colloquium in Torino, Italy in
May 2003. No general agreement emerged from this colloquium.
In parallel, the US delegation to the WP-7A submitted, at the last meeting in
Geneva in October 2004, a proposal which contained the following items:
1 - Maintenance of a time scale called UTC.
2 - Suppression of the leap seconds adjustments which maintains UTC close to
UT1, a time scale based on the Earth's rotation (currently UT1-UTC < .9 s)
3 - The difference of UT1 from UTC should not exceed 1 hour.
4 - The change should take effect at 21 December 2007, 00:00 UTC
If your activity is affected by the content of the US proposal which will be
discussed in November 2005 at the WP-7A, you are urged to react. This could be
the last opportunity before a recommendation is issued by the WP-7A.
If you wish you can express your opinion to your representative(s) at the
