The IBM 360 systems starting in 1964 used the power line frequency. (A
location in low memory got bumped at 300 counts per second. 5 per cycle on
60 Hz and 6 per cycle on 50 Hz.) I wonder how much the power timekeeping

De facto, late 1990s, I think. What one would notice would depend rather
on one's habits; early adopters vs late adopters of NTP.
I should go browse
Does anyone know if the NERC experiment (see below) happened or is still
underway?

From Wikipedia:
Regulation of power system frequency for timekeeping accuracy was not
commonplace until after 1926 and the invention of the electric clock driven by
a synchronous motor. Today

Nice seeing you here!

I am new to this group so please excuse if this subject has been

As I understand the standard ITU-R TF.460-6 the leap second correction
is instantiated globally

It used to be pretty good, because people used synchronous motors to drive
clocks so the power companies tried to keep the long-term frequency correct.
Microwave ovens still use the line for timekeeping. 1/2 :)
I wonder how many old mechanical (synchronous) clocks
