It will be interesting to see how much gear there is out there that derives
time keeping from the line frequency.
I suspect a lot of it doesn't matter much at the second/minute level. (Who
cares if the sprinkler goes on at 6:00 or 6:02?) I suspect there is an
assumption that they have to get reset occasionally, maybe on DST changes or
when power fail or ...

IBM 360s bumped a slot in low memory on each cycle. There was a switch
someplace to select bumping by 5 on 60 Hz systems and 6 on 50 Hz. The net
result was incrementing by 300 counts per second.
These are my opinions, not necessarily my employer's. I hate spam.
