When working in a Microsoft Virtual Machine (VPC or Virtual Server) the virtual will periodically synchronize the clock with the host's clock. This can be a pain when trying to test your code with future or past dates. However, it is possible to stop this synchronization:

 

 

Edit the .vmc file. Find the components tag and add/modify the host_time_sync value to false

 

e.g.

 

<components>
  <host_time_sync>
    <enabled type="boolean">false</enabled>
  </host_time_sync>
</components>

 

 

 

Stop the 1-vmsrvc service.

 

e.g.

 

net stop 1-vmsrvc

 

This will break the ability to copy files into the VM. However, restarting the service will get things working again.
