Thanks to everyone who replied.  I got a few recommendations:

Dan Astoorian, et al.:
It's a known problem; the kernel uses an inaccurate value for the clock
frequency.  Put
    set sys_tick_freq = 5549020

into /etc/system on the Sun Blade 100's and reboot.
This worked great!

Lars Hecking suggested installing the latest patch cluster.  as well as
using Sun's ntpd.  We prefer not to do that, since xntpd has some well
known security flaws.  I tried the latest patch cluster with our version
of ntpd, but it didn't fix the problem.

What I surmise from this is that the clocks on the Sunblade 100's are
not at all accurate on their own.

Thanks again to everyone who replied
