which also means that it is one more bit to set on the receiver (in addition to time zone).

I have many clocks with WWVB time. Many miss signals and become off, one even gets an error once in a while and has the time many hours off. Not all decoders are the same apparently.

Reminds me of the clock I bought which changed MST/MDT automatically, which forced me to adjust it twice a year unlike like all my other clocks, because I lived in Arizona.

Somehow my Casio G-Shock Rangeman cannot do this correctly
