How about "earth day", "earth minute", and "earth second"? Seems a nice parallel to "mars day", "mars minute", and "mars second" that was used by JPL for the probe missions. And instead of "universal time", we can call the earth-tracking time scale "earth time". -Tim Shepard s...@alum.mit.edu _______________________________________________ LEAPSECS mailing list LEAPSECS@leapsecond.com http://six.pairlist.net/mailman/listinfo/leapsecs
