Hrm.
My 7500 (G3 processor) is under nearly 0 load most of the time,
periodically high load (I'm using for a parallel processing project,
but not as one of the nodes, and also to represent eclipsed.net to the
outside world), and I've never had clock problems.
On the other hand, I run xntpd and look at a few strati of servers. My
/etc/ntp.conf:
--- clip ---
# $Id: ntp.conf,v 1.5 2000/02/27 01:18:15 gr Exp $
server 130.58.68.10 # allspice.cs.swarthmore.edu
# contact local-staff@cs.swarthmore.edu
server 130.58.64.40 # acorn.cc.swarthmore.edu
# contact preset@cc.swarthmore.edu
server 128.118.46.3 # otc1.psu.edu (stratum 1)
# contact JohnBalogh@psu.edu
server 128.175.1.3 # louie.udel.edu (stratum 2)
# contact Dave Mills (mills@udel.edu)
restrict default nomodify notrap notrust noserve
# machines in the cluster:
restrict 130.58.82.0 mask 255.255.255.0 notrap notrust
# higher-stratum servers (see above):
restrict 130.58.68.10 nomodify notrap
restrict 130.58.64.40 nomodify notrap
restrict 128.118.46.3 nomodify notrap
restrict 128.175.1.3 nomodify notrap

... and proof that my clock is actually synching (turmeric is a Sun
Ultra 10 running Solaris 2.6, also synching with the servers listed in
my ntp.conf above):
turmeric:~% ssh uriel.eclipsed.net date ; date
Mon Mar 13 14:50:11 EST 2000
Mon Mar 13 14:50:11 EST 2000
So, my response would be "use xntpd", but maybe there's some reparable
issue dealing with macppc clocks that I'm just not seeing here.
