What time is it?

Ever wanted to go back in time to that precise moment before you got convicted? Or to go into the future to find out how Michael Jackson will look like? Well, today's your lucky day! Ms. Mysterious will tell you how to manipulate time: You just have to fly contrary to the earth's natural rotation. But remember:
"After you've finished accelerating or reversing temporal flow, it's very important that you remember to return the planet to it's normal rotation... You'd be surprised how often even experienced heroes will reverse time and then forget to get it moving in the right direction again."

From the book "How to be a superhero"

Heh, heh...
