Hi Lars!

Your expectations? AFAIK XEN does not emulate a hardware clock for each domain.
The command to set the clock in UNIX is "date [-s]". Whether and how the CMOS 
RTC
is updated from the system clock is a completely different issue. I don't know
where a XEN kernel gets the initial time from.

Ulrich
