The Disadvantages of a Free Superpower

Bob: I'm going to press the button. Why would there's no downside here? I can just work on clocks. Do you have a free superpower where you can either joke around or make money fixing clocks? No, that sounds terrible. There's no drawbacks. And how many bar bets you could win if you could change time on a clock? Dude, I'll bet you I can run around this entire block before the clock strikes midnight. That's only one minute from now. Slowly, chug. People have no fun in this world, man. You must be the main antagonist of your favorite book, video game or movie, but you can become a part of that movie.
