My "atomic" wall clock jumped ahead by 20 minutes yesterday

[Hokie]

When I got up yesterday I found my wall clock that is set by the WWVB time signal from Colorado had advanced by exactly 20 minutes. I had to manually reset it. Did anyone else experience this with one of these clocks? This clock has been the most reliable of any of these I have owned. Maybe I went through a time warp?

1. Sure it wasn't the NYC Doomsday Clock?

Only barely "kidding..."

2. Mine was right yesterday and again today. Strange

3. My area has marginal recption of the WWVB signal

I have noticed on the days when DST starts and ends it is hit or miss on whether the clock adjusts properly. I have never had one off by anything other than an hour for DST.

4. Is it battery-powered?

I occasionally have had mine do things like this, but installing a new battery fixed it.

5. Yes, battery powered

The low battery indicator isn't on though. The outside temperature is working fine too. Usually when the battery gets low I lose that first. Regardless, after I manually set it the time is accurate. I expect the Nazi Musk to shut down WWV and NIST any day now.
