Is there any way we could detect the clock-skew problem?  This keeps
coming up, year-after-year, for many different people, including
very experienced developers.  And when it does come up, it is
either:  (1) totally safe, and thus unnoticed, or (2) screws up
someone in the middle of some major upgrade, thus causing great
angst and gnashing of teeth.

It would be nice if we could come up with a reliable check for the
problem.
