Hi, Guy
 Could you have a try of the latest Xen-unstable tree to see if this issue 
still exists? I remember some S3 time patches are added after Xen-3.2 stable 
release. 
Thanks!

Subject: Weird NOW() values after host S3 resume
Hi all,
It seems that something is messed up with the calibration of the TSCs after 
resuming from sleep.
First, after resume NOW() issued from CPU0 gives a value that is much lower 
than before sleep, and it is probably returned to the same (default?) value 
after each resume.
Second, after each resume there is an increased differences between CPU0 and 
CPU1 NOW() values, I'm not really sure about this one because I didn't tried to 
sync my test against the HPET so take that into consideration.
Can you check this out please?
The chipset is Intel GM965/ICH8, the cpu is T7300.
Observed in Xen 3.2 stable release.
Thanks,
Guy.
