Today, I timed my friend to see how long it takes for him to ride his bike around the park. I started the stopwatch. While waiting for him to come back I put on the iPhone. When he came back it showed his time as about 15 hours. When I got home I tried messing around with it and noticed whenever I get out of the stopwatch (not even "Clock") app and go back, the time jumps about 14 and a half hours. I tried resetting the iPhone but still no luck. Should I try restoring it?
