We have a 2012 Server running Hyper-V. I have 3 VMs running under it. Win 2016, Win 8.1, and Win 10. The W2016 and W10 VMs are both experiencing an issue whereby the date/time are rapidly switching back and forth between the host time and some date/time back in 2015.
The problem goes away if the W32time service is disabled on the affected VMs.
We do not see this issue on VMs with earlier versions of Windows.
The host and VMs are only in workgroups.
None of the machines (host or VMs) are a DC.
I've reproduced this exact behavior on another host.
Any input on this time sync issues would be very welcomed
