An alarm clock knows exactly what time to start, by remembering what time you had said to start ringing, and the average alarm clock stops after 1 minute (60 seconds.).

You go to sleep at 6 pm and you set your alarm for 7amhow many hours of sleep do you have?
With an older alarm clock ... one with hands on the front and a wind-up key in the back ... you get one (1) hour of sleep, because the clock doesn't know the difference between AM and PM. With a more modern LED digital clock, you get thirteen (13) hours; the display has that little dot on the side, so you can tell the difference between AM and PM when you're setting the time or the alarm.
If you went to bed at eight in the evening and set the alarm to get up at nine in the morning how many hours of sleep would this permit?
With a "regular" alarm clock, your alarm would go off at nine p.m. and you'd be stuck resetting it to have it go off at nine a.m. You may get 1 + 12 or 13 hours of sleep. Maybe. If you had a contemporary electric (electronic) alarm clock, it could be set for nine p.m. or nine a.m. You'd get 13 hours of sleep without being awakened one hour after setting the alarm. Some of us have been around for a while and used both kinds of clock, and the "original" alarm clocks were around before the snazzy new fangled ones. And we know the drill.
