Clock is 2 hours late after resets

[sono]

Recently, it happens quite often that I restart my computer, and after reboot I find the clock is 2 hours late in Windows 7. What causes this? This didn't happen before.

Hello sono,

Here are some things to check:

1. Have the correct time zone set.
2. See if your BIOS time is correct.
3. Replace the CMOS battery on your motherboard if its dead or weak.

Glitch in the O/S that is changing the time zone at boot?
