I think in 40 years people are likely to remember "TAI" better
than "BIH", and probably "BIPM" as well, but we can take the
long-winded description here, thanks.

But my reply was mostly intended to emphasize that
we're only talking about the name here wrt TAI vs UTC,
and that you're _not_ talking about dropping TAI in favor
of posix as some might suggest.
