Still not found an answer to the five hour loss, but what was interesting was
that when I updated our "clockctl" config file with an active NTP server
(anyone have an enhanced version of this approach that allows for using a
list of NTP servers so we can have some fallback?), the machine said that it
had the correct time all along.  As shown by the date command run just prior,
that was not the case.  Why/how would this happen?  Here is the actual series
of events:

# date
Thu Nov  3 17:15:59 PST 2005
# /etc/clockspeed/clockctl sync
Setting system clock with master server at www.xxx.yyy.zzz:
before: 2005-11-03 22:17:28.182072000000000000
after:  2005-11-03 22:17:28.182235999833472072
# date
Thu Nov  3 22:17:41 PST 2005

That is rather odd, is it not?
