I just bought a cheap electric alarm clock - made in China naturally.
When I plugged it in it displayed the correct time. How does it do
this? Does it pick up a radio signal? The clock works perfectly. I am
just curious.

I have seen both radio signal and pre-set internal battery
powered clocks. It might be either.

I have a couple of clocks that run through the displays on power up,
as if they set the time automatically. Only one of them (then one
that's a clock-radio) actually does. The other uses a little battery
to keep time.
