The clock (and the CMOS battery) got some attention while trying to

If the battery's weak enough to mess up the CMOS, it's possible.
However, long before that, your hardware clock will start to run slow.
(This is, actually a built in feature. It's intended to let you know
that it's time to change the battery.) If you can go into the CMOS
setup, before it tries to boot, see if everything looks right, and that
the clock is right. If it's slow, turn things off without correcting
it, and try again in a few hours. If it's farther behind, change the
battery and see if that helps. I don't know if it's still true, but the
Print Screen key used to work there, and if so, you can use it to get a
printout of your settings to be used later if needed.
