Use command prompt to change date and time
Open a command prompt window. I don't think it requires administrative privileges, but if it says Access Denied after you attempt to change the date/time, close the window and reopen with administrative privileges.
With the command prompt open, type date and press enter. It asks you to enter a new date. Do so and press enter again.
Now type time and press enter. It asks you to enter a new time.
If at either of these prompts, you press enter without entering a new date/time, the date/time will not be changed.
