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).
