Fine. I can believe that. Its about as likely as every other computer 
I've ever owned being blessed by magic pixies to have hyper-accurate 
clocks while everyone else over the last 20 years has been suffering 
from radical clock drift and I've never noticed. I believe your 
statements about the PC clock, and every website I've found says the 
same thing, but its empirically pretty clear to me that this hasn't 
been a problem on most computers I've used, even when they don't run 
ntp.

Yeah, NFS, Make, and our source control (AccuRev) are all super grumpy. 
I started running ntpd, which has 'fixed' the problem.

I don't know if I can afford the time to leave the PC in CMOS, but 
checking hwclock should have the same effect, no?
