Please, no. I've had to spend a lot of time explaining the difference
between GPS time as used in the satellite constellation and UTC as
reported from a GPS receiver.

Unless, that is, when leap seconds are abolished that GPS and UTCng
are to be synchronized. I had intended that as a flippant remark;
but if civil time is to shift to an atomic scale then it will diverge
from solar time. A one-off step of a few seconds would trumpet the
change in time keeping.
