Is that really that case? I would have thought it would only affect
mechanical clocks with synchronous motors, and that all electronic
clocks would use a built-in quartz crystal as their time reference.

Not so. I've got two large LED digital clocks here which are mains locked.
Since they have to run off mains due to the power consumption of the LEDs.

Generally, they're closer to the real time when it comes to have to alter
them when the hour changes than the average cheap quartz one.

Ah, I was mistaken in that case. I naively assumed that modern mains powered
clocks and CH/cooker timers etc were simply a battery-driven quartz clock
mechanism with a PSU in place of the battery. I didn't realise that modern
clocks (as opposed to old ones with synchronous motors) still synced to the
mains.

In that case, it *is* a problem.
