Has it occurred to any of you that *THIS* is the very root of the problem,
that *THIS* is what we need to change?

Also, isn't TAI readily available in real time from GPS? (How difficult
can it be for the routine parsing the data stream from the GPS receiver
to add 19?) OK, OK, it'll be TAI(GPS) rather than "true TAI", but then
your UTC is really UTC(NIST) or UTC(USNO) or UTC(PTB) or whatever rather
than "true UTC".
