 I've seen a similar claim about timers that actually count
cycles-per-second: if those vary then the timer misperforms.

This isn't really an issue in North America. According to NERC[1], frequency in
the Eastern Interconnection (EI) is above 59.972 Hz 95% of the time. This is
99.95% of nominal frequency, or an error of 28 mHz.
If frequency sat that low for a 24 hour period (which it doesn't; frequency error
regularly crosses zero), it would be a loss of 40 seconds in a day.
As a matter of fact, a few years back, the EI had an ongoing problem with frequency
being high: 3 mHz fast as a sustained average over several years. This was considered
a significant enough issue to require an investigation[2].
If uncorrected, it would have caused clocks to gain over 4 seconds per day. This
led to regularly implementing Time Error Correction. In this case, that meant a
coordinated (across the EI) reduction in generation to reduce frequency until the
time error crossed zero again.
Four seconds error per day is considered a problem. If you live in North America,
you can count[3] on your analog clock.
