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 ... > The last system I worked with that relied on 60 Hz power > for timekeeping was a 70's PDP 11/34. 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.
