How many times have you said something like, "I'll see you around 5-ish"..Well, "ish" could become a real time!
Starting in mid-July, your electric clocks and coffeemakers could be running up to 20 minutes fast, and you probably won’t know why.
For the past 80 years, clocks plugged in to an electrical source have kept time based on the rate of the electrical current that powers them. If this current doesn’t keep its usual rate, clocks run a bit fast or slow. Right now, power companies now take steps to ensure the frequency of the current – and the time – is as precise as possible.
