How can that be? If ntpd daemon is running, the server has to be synced
and showing the right time. And in the event the time is too much skewed,
ntpd shouldn't crash but left the time unsynced and registering the error
at the logs (check if adding "-x" argument to ntpd helps here).

IIRC, you mentioned that after the crash, ntpd could be restarted again
without problems. If that's true, it means at the time ntpd daemon is
started, the time of the server is still close to a good enough for ntpd
can be launched without manual corrections.

Becasue ntpd crashed?

Virtual machines do suffer from time sync issues so maybe a clusterized
environment can also be affected somehow :-?

You can change the CMOS battery to see if that makes a difference but a
death or bad battery would also have caused additional side effects such
as motherboard settings restoring to defaults values which is not the
case.
