Not really time change related, but reminds me of prank we have played on some lease members in the past. After one of the guys falls asleep early, we fast forward his alarm clock so that he thinks the alarm is waking him up at 5 a.m., but it is really 11 p.m. or midnight. We wait until he gets fully dressed and ready to go before we let him in on our joke.
Had this done to me, a dead hog ended up in someone's truck that night and they didn't notice it until halfway back to dallas.....joke was on them.
