" Close, but not identical. The hwclock time will be written back
" periodically.

How periodically?

" Bizarre. Anything unusual about this machine compared to the
" others that are OK? 

As of now I am getting repeatable time jumps on 4 of 16, plus another 3 that
jump occasionally but not always.

The machines are all IBMs.  IBM x330, x335 and HS20 blades.
The repeatable hosts have 1GB of mem.  THe hosts with only 512 or
256MB ram don't seem to be affected. 
How could memory size matter?

They are running 2.6 in xen0 and xenU, and use the latest sarge
distribution from Debian.
