Time on desktop keeps rolling back one hour

[NeezyDeezy]

Every now and then, when I restart my computer, during bootup it changes the time to an hour before what it should be. When I go to adjust time and date (I use windows XP), I can do so, but the next time I reboot it changes.

I've tried adjusting the time in BIOS also, but just the same thing inevitably happens. It's driving me crazy because I never can be sure what time it is unless I look at my phone and it's made me late once when I really shouldn't have been. Can someone please tell me what might be causing this and how to fix it? Thanks!

Probably you don't have "Automatically adjust for daylight savings time" checked in the data/time section.

Are you in your correct time zone?

Just to be on the safe side, replace the CMOS battery on the motherboard. They are usually a CR2032 type battery.

So....

1) Replace CR2032 CMOS battery
2) Adjust time & date for correctness in accordance with OP's time zone (BIOS)
3) Boot to Windows, and insure your time zone is set accordingly

I have seen this problem twice with software.

one was a free game that a student wrote (space invaders clone )with a bug in it. every once in a while I would play the game and move on and maybe a day or so later discover that the system clock was wrong. Turned out everytime I played the game it reset the system time to 12:00 that was on win 98 as I recall.
********************************************************
A couple of years later I bought a compaq and it worked fine for a year or so then I started noticing the time would start out right , but as I went about the day somehow it would get off by 20 minutes.

After a lot of careful observation, I noticed that upon connecting to the internet if I watched the clock display it went back 20 minutes as soon as I was connected.
That gave me finally an answer of when it happened , but not how.
I then went into the mscfg and turned off one start up , rebooted and connected to the internet. clock went back 20 minutes still.
I rechecked that startup and disabled a second startup and repeated the process all the way down the list one by one.
Finally I found if I disabled a certain one of those that the time alteration ceased upon connecting to the net.
It turned out to be a compaq utility that came with the machine. I forget which one seems like it was called Digital Dashboard or something like that??? this was several years ago. Like Windows Me I think?
Anyway I left it disabled and it quit screwing with my clock.

Is this computer on a domain?
