[Powers] Rewind Time

I have two major questions:

1. How would you model the ability to rewind time short distances (up to a couple minutes at most, but, while I'd allow repeating the same jump over and over, I'm thinking you can't get past the 'up to a couple of minutes' problem by doing repeated jumps in a row)?


2. How would you handle such an ability as a GM? How would you keep track of where the "reset point" was at any given point in time?
