[time-nuts] 60 Hz measurement party

[Bob Camp]

Hi

Doing something similar in the mid 1960's we noticed that the local power company did time correction just ahead oft 5 pm. You could start listening to the time ticks on WWV or CHU at 4 pm and see them do the correction over the hour. For what ever reason their daily correction was at least a couple seconds. In a few cases people reported stuff at > 5 seconds.
