Hmm, I think the Time Services got adjusted by about four minutes. I have six manually set clocks that are all within ten seconds of each other. They were reset Sunday, based on the time on my cable box. Now the cable box is slow by four minutes. And since my phone, my iPad and my wife's phone and all my computers match it, Time Services had to have been adjusted. It's just not possible that the microwave, stove, grandfather clock, dad's old hand built digital clock, my LED alarm clock from 1978 and a weather station all jumped ahead four minutes.
