Another question: why does the alarm clock blare non-stop until you turn it off, rather than beeping a couple times and then going silent, giving you a moment to get up and turn it off without annoying the living hell out of everyone who doesn't have to get up?
Current theory: alarm clock designers never marry.
But when they do they may end up with their own alarm clock that is impervious to logic, programming or reason.
For a notional 7am setting our little alarm clock wakes up one of us (a seemingly random choice) usually sometime between 6.15am and 7.15am. Very occasionally it malfunctions and wakes us both up at 3am.
Also, this ensures the alarm clock does its job - either you wake up yourself, or your angry family members wake you. Both ways, you get up when you wanted.
The TIMEX clock I've been using since college has 8-minute intervals, and the alarm clock app I have on my phone has 10-minute intervals by default.
The snooze was on 8 minutes but I could press the snooze button multiple times to increase the time. So if I wanted a 24 minute snooze I could wake up and press it 3 times and it would go off in 24 minutes.
But! What alarm is this? It sounds wonderful. Mine is pretty old and starting to die / possibly flaky, I might have to pick one up.
