Seconded.  FreeBSD will give you better timekeeping than Windows.  If
the difference between a few microseconds and a few hundred
microseconds is no problem, my recent Windows releases are fine.  But
if you're dedicating a small PC to the task, care about those
fractions of a millisecond, and can manage FreeBSD, it's the gold
standard for NTP.
