The clock

John was very tired after a long day of work. He went to bed at 10 p.m., wound his alarm clock and set it for noon the next day. Since John fell asleep almost immediately, how many hours of sleep did he get before the alarm woke him?

Only two hours...if he would have had to wind the clock, then it would mean that it was only a 12 hour clock, so it would have actually woke him up at midnight...
