This is not true. It does change a bit under heavy load and the req. to keep it constant are far from perfect. There are timers that use the AC freq. but they are far from precise compared to a quartz crystal oscillator ones. A low effort [0] stackexchange search.

- ultrarunner 4y agoI don't exactly keep up on these things, but at one time off-peak frequency compensation was done specifically to keep AC-synchronous clocks accurate. I wouldn't be surprised to find that's not really done anymore.
