Try this
1. Start->Run cmd.exe
2. net stop w32time
3. w32tm /unregister [ignore error message]
4. w32tm /unregister
5. w32tm /register
6. net start w32time
This is a very common issue that Dell computers have (though other makes may
have the same problem too).
DELL [or someone else] could have imaged the OS from one machine and
installed in on a batch of machines notably with different CPU speeds.
Information about the imaged machine's processor clock is stored in the
registry. The defect is that windows should detect that the processor is
different and should refresh the registry entry. The steps above force that
to happen.

Every time I set the internal clock-within 24 hours the clock loses
three
hours. Oddly enough, it never loses more and never less than three hours
and it's always three hours. I repalced the battery and the same thing
happens. I reset it daily and the next day I lose the three hours again.
Ideas??
