Windows Hyper-V Server Host Losing Time

Hi all,

I've read loads of stuff on the internet about time drift etc. on guests. But in this case I have the opposite problem.

I know that technically speaking the "host" OS is also a a "guest" VM running on the Hypervisor.

My VM guests are all synced with a Physical DC on our network and time sync services from Hyper-V are disabled, so they are all OK,

But even when the host OS is synced with this DC it still loses time, about 5 seconds a day.

Anyone got any suggestions?

TIA, Adam.
