Don’t forget that you get that extra hour of sleep Sunday, marking the end of Daylight Savings Time. So, set your clocks back an hour. . . even that one clock that you always forget.
If you have an atomic clock, leave it be. It will take some time (no pun intended), but it will come around. And, no, an atomic clock does not run on atomic power. You’ll still need to check the batteries.
And don’t forget to change the batteries in those smoke detectors.
