This is a separate thing, timesync registers itself with the vmbus so it receives
a time sync message from Hyper-V on cold boot and restore from saved state.
With this we set the clock on the current VM. (Human readable time basically)

What KY submitted it a driver that connects to the Hyper-V stable timesource.
There are no messages from Hyper-V for that, you have to read that directly
from the hypervisor page.
