In the USA, it's a very accurate 60Hz, but if it drifts at all, during the 
last minute of the day, they adjust the frequency to get exactly the right 
number of ticks in. Probably because of the alarm clock thing, if nothing 
else.

It might need to be more regulated on three-phase wiring, and I don't know 
if the frequency is different between the generator and the wall-socket 
(altho I doubt it), so I'm not sure just where the accuracy is enforced.
