Hi, Scott,
Here in New Orleans a friend in the power company who was interested in
its history told me a story. In the very early days, frequency control was
pretty poor and it was hard to keep up with the changing load. So by 5 PM every
day, every electric clock in the city was 10 or 15 minutes slow. So overnight
they'd speed up the system and so by 8 AM the next morning every electric clock
would be 10 or 15 minutes fast because the total slip during the day was 20 or
30 minutes.
Good story. Hmmm,
If I was the power company boss I'd have given all my employees a
nice shiny mains clock when they joined ...
