Yes, it does.

I am inclined to doubt that, because (a) if the clock is stopped the
POST code restarts it and (b) I've yet to find a Sun with anything
predefined to stop the clock.

For them as wants, here's my cheat-sheet of how to stop the clock on
various machine types.  Machine types in [brackets] are ones I
conjecture are correct (I've found it said somewhere, usually) but have
not personally verified.  I usually wrap these inside

: stop-clock ... ;

and stick them in nvramrc, with use-nvramrc? set true.  (This requires
a non-dead battery, of course, but if the battery is dead the question
of stopping the clock on power-off is moot.)
