A technical thought.

Most such devices that have electronic clocks in them to come on at certain times will reset and stop the alarm function (and sometimes reset the time to 00:00!) if the mains power is "lost" :-) for a while. There can be 'backup batteries' inside to keep the info a for a few hours.

'manual' time switches (that use mechanical clocks) would not be affected this way.


Say no more, say no more, nudge nudge, wink wink...
