It used to be common for clocks to be driven directly off the electrical frequency. The US Navel Observatory would call up generator plants and tell them to slow down or speed up a little to make a correction to all the clocks. I'm not sure if that still happens, though.

I've heard that trope before, same reason clocks in US schools/govt institutions were always plugged into a wall, hence these. Nowadays, NTP has rendered that obsolete.
