Re: Changing System Clock

While Oracle does not care about time changes, cluster daemons do - so if you're running veritas, RAC, 10g RAC, etc. do not use ntpdate to change your time.

If you use standard ntpd, it does not change the time, but rather will slow down or speed up the time very slowly over the course of many hours or days until the time is in sync. Ntpdate is useful for initially setting the time, but you should use ntpd to keep the clocks constantly in sync.

Thanks,
Matt
