This is not correct (per USNO).  "GPS Time" is traceable (in NIST usage)
to UTC(USNO) and hence UTC.  The GPS message carries the current offset and
USNO produces retrospective reports.  It's worth noting that that "GPS
Time" may not be legally traceable to UTC outside of the US since the USNO
is not an internationally "recognized" national metrology institute.  That
would depend on case law.
