Another suspicion I have is that NTP is sensitive to network I/O on
Windows. There are some large fluctuations with NTP that coincide with
nothing other than network activity - and nothing more than 5% or so of
I will be away from home starting this evening until Monday. There
should be no network activity other than that initiated by someone
accessing my Web server, or NTP itself. It should be interesting to see
what NTP does on a machine that is not being used at all.
