W32Time synchronizes clocks within a forest using a time hierarchy that begins with the PDC Emulator in the forest root domain, which is considered the stratum 2 time source for the forest. This domain controller can have its own clock controlled several ways:
-By synching to a reliable time server on the Internet.
-By synching to an locally-connected hardware time source such as an atomic clock.
-By relying on its own internal CMOS clock for reliable time.
i would start of by changing the CMOS Battery…see if that helps…
