WWVB is not generally useful for precision timing applications, due to the distance and wave reflections. Also, from a security point of view, I have read that it is legal to have your own low-power transmitter on the WWVB frequency, and there are instructions for doing it with a Pi, so it would be very cheap and easy to mess with somebody's WWVB signal. -- Chris Adams <[email protected]>
