Event viewer+some programs show the wrong time

[Celeras]

Just got a new mobo/CPU, installed, everythings fine. I'm unsure if this problem was on the old hardware.. if it was I never noticed it. Overclock test time, so I run prime95 and go do some errands. Come back to the computer rebooted, no problem.. thats why we test. I go into event viewer, and notice all the times are 12 hours too fast. Things I did at 7:30am, are showing up as 7:30pm. Things I did at noon, are showing up as midnight the next day. So I check Prime95 results:

I'm in EST, and I started running this test on 6/26 around 11am. It appears that the reboot happened around 12:40pm... This clock is too 12 hours off it seems. Military time confirms it actually just is fast, and not an am/pm display mixup.

System clock is correct. Time displayed in bios is correct. What's the deal?

Hi Celeras

Not sure f I could be of much help but have a look at this thread in relation to time-synchronization. You could try that to see if the issue persists.

Did you download/install any Windows-updates for your OS recently?

Checked the thread, my time sync is accurate and up to date.

I have not installed any windows updates after installing the new hardware no.
