Restrict Windows System Time Modification

Using Group Policy on Windows it is possible to block the ability for users to modify the system date/time.

In the Group Policy Editor, navigate to:
Computer Configuration -> Windows Settings -> Security Settings → Local Policies → User Rights Assignment → Change the system time

Remove any users or groups that do not need this permission.
