I think you misunderstand my setup.
VM 1 serves the Apache installation, and VM 2 runs the Tor hidden service.
Therefore as far I understand Only VM 2 must have its clock correctly set.
VM 1 on the other hand serves the Apache installation, and there is no
reason why the date, time and timezone of respectively VM 1 and VM 2 has
The connection between VM 1 (Apache) and VM 2 (Tor listening on the
internal hidden service port)is socks 5, and there is no outbound internet
connection permitting any timesync or Microsoft service to break out of VM
An attacker attempting to correlate the time of my server (through a HTTP
request) with my Tor machine will only retrieve the date, time, and
timezone of the (virtualized and locked down) Apache installation.
