How do I change the upper console clock on my '02...

Question

I just got my jeep and I don't have an owners manual. How do I change that clock on the upper digital console above the rear view mirror? I press reset and it goes to 00:00 then counts real slow, but I cant find a button that makes it set, and I doubt they expect you to wait until those numbers go all the way to the current time! That would take like 10 min.
