I have a VPS that runs Windows Server 2008. The time keeps changing every so often. I haven't been able to find out what triggers this change, but it's usually forward or backward several hours at a time. I don't think the minute changes, it seems that only the hour changes.
Windows Server 2008 keeps changing time by itself

The VPS is probably configured to set the time of the VM's it's hosting, and your Windows 2008 VM is probably getting time from the default time source (time.windows.com)... Try disabling your VPS from setting the VM time and see if that fixes your problem.
