New to the forums. Cheers ppl!

As you can see, I have a bit of a problem, and maybe Im just too damn tired to see whats right in front of my face, but I cant seem to get it.
MMC is displaying the wrong date when I open it up. Today is Tuesday @ 8:22PM, but my MMC says its Wed. @ 8:22PM on the welcome screen.
Is there a way to change this default date? Because I think its also messing with my Guide Plus
Im using version 9.15
