I don't run Linux-AFS at home (over a 28.8 modem connection? I may be weird
but I'm not *crazy* :-) --- xntpd synced my system this morning while I
picked up mail, so the time was correct:

Dec 2 06:44:26 rushlight xntpd[336]: time reset (step) 50.691801 s
Dec 2 06:44:26 rushlight xntpd[336]: synchronisation lost

The system sat idle from 06:58 until 17:06; I had an idle X11 session, the
only thing running was xscreensaver. But this afternoon:

Dec 2 17:31:00 rushlight xntpd[336]: time reset (step) 42.043875 s
Dec 2 17:31:00 rushlight xntpd[336]: synchronisation lost

(My system at home usually loses time, but occasionally gains instead.)

This is relatively stable compared to what it did when I first installed it;
the numbers ranged from a gain of 38 minutes to a loss of over 3 hours (!).

Red Hat 5.0 with kernel 2.0.33 built from pristine sources (*not* Red Hat's
patched kernel). Uptime 8 1/2 days so far (a circuit breaker took exception
to a light bulb burning out --- running power cables all over the apartment
to get things on different circuits annoys the landlord...).
