Clock on All Domain PCs moved ahead 1 hour

March 26, 2011 at 10:30:54
Specs: WindowsXP or 7
i have a very strange issue here.

where we live we had a power outage the other day.

since then all users PC' on the domain move ahead exactly one hour.

if i change the time in the BIOS it stays correct until the user logs on.

if i change the time in windows it reverts back to 1 hour ahead in just a few seconds after being changed.

it does this on all 20+ PC's.

all the workstations do not have an internet time tab on the adjust date/time settings.

the server time , barracuda web filter , & router all have the correct time and are the only thing to do so.

i ahve never seen anything like this nor can i seem to find out anything about it.

does anyone have any ideas ?????

your help would be greatly appreciatied.

PS this happens on both XP and Win7 machines.

Are they in the right time-zone still, it sounds like they are adjusting for daylight savings for the time zone. Under time settings you can see if it is checked off to sync with the windows.update time clock or gov't clocks.

Try it unchecking the sync function and see if it keeps the time.

I am wondering if you are setting the time, then they check (sync up) with windows time clock and reset on you. Make sure the day, year, time zone is correct.

yes time zome is correct....P.S.T

date is correct and does not change.

just the PC's.

not sure as to where they are getting the time from aside of the BIOS clock as none of them have the 3rd tab to sync with time clock.

if it was the server, the time is correct on that machine.

and it's only been a problem sine the power outage the other day.

all PC's . OS's , exactly one hour every time but it stays at the 1 hour ahead never goes beyond.

and i have nott ben able to find any other issue like this on the internet.

thanks and look forward to any help or idea's that anyone might have.
