Hello Lord_Nikon,
You should be able to set the date/time manually to resolve your issue, you may also need to set the correct date/time in your system's bios settings as well. I would highly recommend checking the date/time in your bios first (please refer to your system's owner manual for information on how to do this) before changing your Windows time. Please let me know if you have any further questions or concerns.
Thank you,
Matt Prall, MS
