why does my computer clock run faster than normal time?

[Spooner]

i am constantly noticing that my computer clocks runs about 5-7 minutes faster than my normal clock. even when i change it back, it takes about 3 days to get back to being fast again.

Windows XP is prophetic!

Replace your mobo battery.

Probably need a new CMOS battery.

EDIT: Dang, just beat me.
