If you have a clock with a drift of 100 ppm, which is very normal,
and a poll interval of 1024 seconds, you're basicly off 102.4 ms
every 1024 seconds. ...
On consumer grade equipment, drifts of more than three times that
amount are not unheard of. I've had to resort to things like this:
root@p75:~ # /root/adjtimex --tick 9996 --freq 3550100
Pissing contest? I have to do --tick 10025 on an ASUS motherboard. I
thought ASUS was quality stuff, but the clock generator seems to be
crap.
I don't know if 9996 can be handled by ntpd, but my 10025 was
definitely too much. It was continually resetting the time.

Maarten
