If you are in the USA, your clock must have a time zone control (or be fixed to one time zone), because the WWVB signal broadcasts UTC.

Ah, hunting the serial number led me to discover that the clock is part of a centrally-synchronized wireless clock system. The company is discontinued, so who knows how old these are. So I'm going to hunt down a wireless transmitter somewhere in the building that is setting my clock four minutes fast... Oh well, I don't get to try out OP's cool tech!
