I have one machine that always drifts forward, at least 3 minutes/day, and
sometimes up to 10 minutes/hour. The worst long-term drift I've seen from it
was when I was on vacation for and it was basically idle for 11 days, during
which time it slipped forward over three hours. I started running XNTP on it
after that, so don't pay much attention any more, but XNTP does have a devil
of a time keeping it synchronized sometimes.

Just to muddy the waters even mroe: the machine started out running Redhat 4.x
(4.2 I think), and is now running 5.1. It's a production build box, so it
always runs the stock RH kernels.

I don't know anything unusual with the hardware; it's a triton II motherboard,
200mhz pentium, IDE-based PC.
