I also had a problem with this, however on my setup for some reason it
would still revert the time to Jan 25th 2009 every minute or so,
presumably ntpd didn't know what to do with the time that far out of
whack.
sysctl xen.independent_wallclock=1 didn't seem to do anything, so i
changed sys/i386/xen/clock.c
if (shadow_tv_version != HYPERVISOR_shared_info-wc_version) {
to
if ((shadow_tv_version != HYPERVISOR_shared_info-wc_version)
(independent_wallclock!=1)) {
Kludgy i'm sure, but it stopped the Jan25th thing. My time still skews
slowly, but ntpd should be able to adjust that without changing ntpds
tolerances.

Hi björn,
and don't forget configuring activating 'ntpd' within the domU ;-))

Hi Björn,
This is a known problem (see other mails on the list)
The only workaround at the moment is setting this in the dom0:
sysctl xen.independent_wallclock=1

Hi,
with CURRENT FreeBSD kernel I have the problem that time periodically
jumps
back to Sep 16 08:46. That happens every couple of minutes. I set up a
cron job
setting the correct time via ntpdate every minute but that is a
problem when
the time jump happens during ntpdate is just running - it hangs then.
There is
no cpu and no io load on the machine which might correlate with the
time jumps.
Any idea what might cause the problem? XEN is 3.2.0 with Linux Dom0.
