Clock Stopped At 3:13 AM

Its round about that time that those who are going to die in bed, do so, the human body is at its lowest that time of night, I wake up mostly at that time, defying death perhaps?

That is odd.

What does it mean?

Also stuff fails just, well, because.

Just personal observation, I've never seen a digital clock stopped before. If it powers off for some reason it flashes 12:00. But just stuck on a time?

Not that it doesn't happen, of course.

An oscillator with a very controlled frequency is at the core of all digital clocks.

Usually this is a quartz crystal resonant circuit - a feedback loop feeding the amplified electrical oscillation back into the crystal in such a way as to "lock" the oscillation frequency.

If anything in the the oscillator circuit fails, the counter stops incrementing, hence the display does not update.

Simple!

The digital display circuit is different from the oscillator circuit. The oscillator is a vibrator only. Nothing loops back into the oscillator, it outputs only.

The display is based inside a counter timer chip, it could freeze, just never seen it.

If the signal is interrupted for some reason, it will start an error routine and begin flashing to indicate a malfunction so you know to reset it.

Never seen frozen, personally.

I don't think it's real, at least i hope not

I read something, years ago now, about how if you wake up repeatedly at a certain time over a succession of days, someone (something?) is likely watching you. Probably not credible at all, but interesting to think about.
