 Soon power companies will remove long term grid frequency drift control. Engineers have long known that the 60Hz line frequency is a stable long term clock source. Many older consumer clocks derive their clock base from the power line. This is a cost cutting measure. From the unofficial info I have seen the frequency may drift as much as 8-20 minutes per year. The original story was reported in the Associated Press. |
