When you use HyperV or any virtualization, you want to remove the time syncronization that the child has to the parent.  The reason is you want that child, especially if that’s a domain controller to sync independently.  In my case I also had to set up time sync on the parent as well as it was drifting.  To the point of badly.  So uncheck that box, and don’t sync the time up to the parent and then that child server will independently sync to an external time source as it needs to.

    Thanks. Should have spotted that myself!
