Right after rebooting I get this:

# clock -r
Thu Apr 13 23:48:28 2000 -0.117809 sec
# date
Thu Apr 13 23:48:31 MDT 2000

Now I let the screensaver take over, and about 12 minutes later I get:

#clock -r
Fri Apr 14 00:13:31 2000 -0.711014
# date
Thu Apr 13 18:13:35 MDT 2000

Well not only is the SW clock slipping, it is going back in time! So it
appears that it may be the APM. Is it possible to turn that off?

Well, rebooting works, but that is rather drastic.

Well that is better than rebooting.

Gee thanks. It's pretty bad when I can get a reputation for interesting
problems when I don't want them in the first place.  :)
