A calendar, made up of days, which because of the leap seconds are kept in the traditional agreement with earth rotation. Thus the other POSIX quote about not all second being the same duration. Which is to say that POSIX has effectively rejected the reasoning of the winners of the 1960s version of this argument who were adamant that maintaining uniform frequency was paramount. Rather than invent a new terminology for what that is, the authors of the PostgreSql manual simply say that the database time scale is UT1. They could just as well have said UT2, or UT, or GMT. And that opens up a whole other avenue for animated discussions about details that are not relevant for the ITU-R decision. -- 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
