How large ought drift to be.

| I am running ntpd using ntp-4.1.2-0.rc1.2 under RedHat 9 running dual 2.8GHz
Intel Xeon processors in a Dell Power Edge 1600SC server,
/etc/ntp/drift stabilizes to around 100. I understand this to mean 100 parts
per million = 9 seconds/day = 53 minutes/year. That strikes me a large, even
for a cheap digital watch.
Is this some kind of an artifact of the kernel or of ntp? If not, is this an
acceptable drift for the hardware clock? Is it something I should worry about?
Does it bode trouble for me as the board ages? Should I complain to Dell?

Someone just posted a response to a similar issue with Dell's running
SMP on Linux. It involved replacing the BIOS. See the message for
details.
