Why is computer clock changing time?

It would seem like once a week, the internal clock on my computer loses exactly 2 hours for apparently no reason at all.  I change it back to the correct time in the bios and it's ok for a time.  Any ideas?

There's a small battery on the motherboard which stores this and other information when the computer is switched off, more than likely this is beginning to fail. There very cheap and easy to replace, instructions here.

And what it looks like:

If your unsure though I would get someone who knows what they are doing to swap it for you just in case.

Hope this helps!

My computer is less than two months old; do you think could possibly still be the battery?

I think that the synchronization with the internet time server was the problem.  When I went to the clock and checked the internet server, there was two hours difference.  Also, my time zone was set incorrectly.  When I changed that and synch'ed with the internet, all came in line.  I'll keep my eye on it for a week, when it synchs again.  Thanks for your help.

Did you Check your time zone?

As an aside to garethh86, there are 4 'standard' time zones across the continental US, eastern (-5), central (-6), mountain (-7) and pacific (-8). That doesn't include Alaska (-9) or Hawaii (-10), of course.  Decrement each of those GMT corrections by 1 during daylight savings time, which we started this past sunday morning. Hope that helps!
Cheers Darr247, always thought there were just two :)

This is deffenately the issue dldoug, the machine will synch its time settings evey so often which is what will be setting the time back.
Force accepted.
