We do not want dom0 telling Qubes-Whonix VMs the time. Because in case of a compromised Whonix VM, we do not want the adversary replace/restore the /etc/qubes-rpc/qubes.SetDateTime script. To avoid time related deanoymization. We need to stop dom0’s /usr/bin/qvm-sync-clock from running that hook for Qubes-Whonix VMs.

In T384#6287 @marmarek said we should use the mgmt stack for that.

mgmt should keep configuring qvm-sync-clock disabled for Qubes-Whonix VMs. For freshly downloaded templates as well as for user custom created new Whonix VMs based on Qubes-Whonix templates.
