Thanks for the link to the VMware time document. I've seen that before, and it's an excellent primer for time issues in virtual environments. Unfortunately, as that doc rightly points out, there's no standard way for determining time. I predict drift will be making huge comeback, even on supported ACPI-aware OSes. A few more posts on that in a bit... @ Chris…

Expect lots of clock drift on unsupported ACPI-aware OSes (Linux, FreeBSD, etc) running in Hyper-V. VMWare have a good <a href="https://www.vmware.com/pdf/vmware_timekeeping.pdf" rel="nofollow">timekeeping document</a> which provides some good background on how it all works and what VMWare Tools actually does. Still waiting with bated breath for MS to document this as well as VMWare have done... And it’s generally ACPI-aware OSes that have the most amount of grief.
