The National Institute of Standards and Technology and WWVB encode
a special DST "bit" in the WWVB transmission for DST. Your clock will
read this information and automatically advance the hands one hour in
the spring and eleven hours in the fall.
Arizona: If you live in an area that does not recognize DST, you must
press the DST button one time only to turn OFF.

Signal Interference
In some cases, the signal is affected by weather conditions and electrical
