My radio-controlled Acu-Rite wall clock is supposed to be synchronized with the NIST Atomic Clock.

All the Acu-Rite has to do is receive the signal from that one station, WWVB in Fort Collins, Colorado. Apparently, it wasn’t paying attention last night, when Daylight Saving Time kicked in.
Maybe it’s bothered that the station’s call letters aren’t KWVB, despite being west of the Mississippi River. Or perhaps the clock doesn’t like Daylight Saving Time because of Colorado’s proximity to Arizona. Wait. Did Trump tell Elon to turn off the signal?
