Sorry for multiple emails. I sent the last one from the wrong address.

Can anyone please tell me if the value returned by a time querying instruction like gettimeofday() on a Xen (Linux) HVM is the true (System) time or the Domain-virtual time?

PS: Domain virtual time is defined as the time that progresses at the same pace as cycle counter, but only while a domain is executing. It stops while the domain is de-scheduled where as System time accurately reflects the passage of real time.

I am facing issues because my HVMs show a time drift.

Thanks
