Completely disable Date and Time sync in a Hyper-V VM

Solution 1:

How about unchecking Time synchronization option in Integration Services under VM settings?

Solution 2:

Hyper-V guests always synchronize time with the host on BIOS level during boot. Try to specify the time zone properly, otherwise you can manage time in Active Directory.

Hope it helps.

Solution 3:

In addition to the answer that suggests to stop "Windows Time" and "Hyper-V Time Synchronization Service", I found that you not only need to stop it, but to deactivate the "Windows time" service. If not it will be restarted.
