Hello everyone!

I been observing some peculiar time drift on my Xen domains (dom0 and
domUs).  The time (as returned by timeofday) on my domains drifts at
an almost steady rate from the real time ( as read from the time stamp
counter ).

The drift is so constant that it makes me think there should be some
simple explanation for it in the way Xen keeps time.

Some info about my set up:
guest OS: ubuntu
independent_wallclock is set to default 0 on all domains
no NTP synchronization

The drift is around 50 microseconds / second on all the domains. Has
anyone else observed this? If anyone can point me to some
documentation that explains this behavior, that would be great!

Good day!
