Actually, GPS time is pretty ugly mathematically, as it has to make relativistic corrections for time dilation due to speed of the satellites and for gravity-well dilation (which are in opposite directions).
That's how GPS _calculates_ the time, but "GPS time" (i.e. time as reported by GPS) is a constant offset from TAI (TAI - UTC as of 1980). -- Chris Adams <cmadams () hiwaay net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
