Check your time and date setting in the bios! If that wasn't set correctly it could be forwarded on time and date there. You may as well go into the control panel settings and look those if you never set the time and date there.
I use Everest Home edition. It has been discontinued now. Check the link below to download a copy. It will tell you a lot about your system.
