It depends on the accuracy requirements you have. Getting high accuracy
under Windows can be pretty tricky.
Some days ago tvb asked me off-list about details on timekeeping under
different Windows versions, and I've put some information together here:
I've also put some measurement results together, which you can find here:

(ntpd) from ntp.org has been designed for long-term operation. It tries
to determine the clock drift of the local computer, and compensate it.
The Windows port also includes a couple of workarounds for limitations
in the Windows kernel, and IMO yields very good results under the given
