There is no snooze button. If you unplug it, a battery takes over. As wake-up time approaches, you cannot reset the alarm time.
It could be the world's most exasperating alarm clock.
Once it goes off, to stop it you must get out of bed, go into the kitchen or bathroom, and punch the day's date into a telephone-style keypad. That's the only way to stop the loud 'ding-ding,' designed to sound like a customer angrily banging on a concierge bell at a hotel.
My suggestion for a heavy-duty version: the user must solve a basic algebra problem before the alarm turns off.

It gives you a snooze, though, so it's not as extreme as this one. And I'm pretty good at math, so forcing me to input the date would probably be more difficult.
