In other curious timing, it was only earlier this year that TF.536 was suppressed by the ITU-R http://www.itu.int/rec/R-REC-TF/en but it was also the case that in 1978 the CCIR approved recommendation 535. TF.535-2 is still in force http://www.itu.int/rec/R-REC-TF.535/en and just as it did originally in 1978 it asserts that the basis for the ITU-R usage of the term UTC was established by the CGPM in 1975 and the IAU in 1973. Both the CGPM and the IAU recommendations explicitly recognized UTC as mean solar time. Therefore the standing documents of the ITU-R argue against any change to UTC which would make it not be mean solar time. -- Steve Allen <[email protected]> WGS-84 (GPS) UCO/Lick Observatory--ISB Natural Sciences II, Room 165 Lat +36.99855 1156 High Street Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 http://www.ucolick.org/~sla/ Hgt +250 m _______________________________________________ LEAPSECS mailing list [email protected] http://six.pairlist.net/mailman/listinfo/leapsecs
