My constantly disrupts date from 2008 to 2002

[PeterT]

Hello
OS: Windows XP SP2
For some time my date becomes deregulated constantly from 2008 to 2002. My machine is always supplied with energy I think its should not be the CMOS battery.
When I rule the date after a time the date changes again. In fact only one year of change.
I also stopped the clock windows but there is nothing
The program that I installed between the period or everything was fine and it is not going zone alarm.
Today I can not go on the net without changing my date. or connect to MSN. It's embarrassing.
Thank you for informing me if you have any solutions to offer me.

Zone Alarm is a Firewal => nothing to do I think. I used a few years without ever experience this kind of problem. Incidentally, with the current box using a firewall is justified only in very special cases I think.

Thank you, I'll check my CMOS battery.

especially if it's after dark and turned back the date blocks

In fact the date blocks all the time. Not only when I turn. After he settled change after 20 minutes max.
