I would like to thank foxidrive who has provided an alternative Windows 8 approach to change and revert the date. Both bfollett and my testing of it worked and seems to be a universal Windows 8 approach. An added bonus for both of us was we did not need to go through the extra step of setting the BSLoader to Run as Administrator.

I will upload the newer BSLoader sometime over the next day or two. I might also add some more variation of the delays before reverting date back to today so people can use a custom delay to suit the speed of their system.

Edit: foxidrive provided a variation of the above to cater for various date formats which I may or may not end up using.
Edit: works for both bfollett and I so will be used instead.
