Games are timed in real time but an in-game time variable is also available. Since the in-game timer only records the "first" clear of each level, it will need to be reset before each run. This can be accomplished by simply deleting and reinstalling the app. Don't worry, all your GameCenter points and purchases will not be deleted, and any level you have previously unlocked will still be unlocked. The only things deleted by doing this are the statistics of time taken to beat a level, number of deaths and attempts, and number of jumps. In addition to providing a more accurate timer, this also allows for you to record how many jumps and deaths were in a run. If two runs have the exact same time for any category, the priority will go to the run with the lowest number of deaths and then the run with the lowest number of jumps.
