The group that oversees the U.S. power grid proposing an experiment that would allow more frequency variation than it does now without corrections. The experiment is tentatively scheduled to start in mid-July. Unfortunately, this can mean that some clocks will not keep time accurately. According to US Today:
Since 1930, electric clocks have kept time based on the rate of the electrical current that powers them. If the current slips off its usual rate, clocks run a little fast or slow. Power companies now take steps to correct it and keep the frequency of the current — and the time — as precise as possible…
…No one is quite sure what will be affected. This won’t change the clocks in cellphones, GPS or even on computers, and it won’t have anything to do with official U.S. time or Internet time.
But wall clocks and those on ovens and coffeemakers — anything that flashes “12:00” when it loses power — may be just a bit off every second, and that error can grow with time.
Of course, homeschoolers are notorious for being late, so now we have one more
excuse thing to make us late.
