Date/Time jumps after correct setting of date/time/timezone?

[aepm]

Have set the correct time zone, set the date and time, and within half an hour, the time jumps ahead significantly. Time then continues jumping periodically, and date as well. Any patch available for this?
Thanks.

Perhaps a change of cmos battery is needed. What is happening is a sign of the battery having packed up.
