[Elecraft] OT: WWV-driven station clock that displays zulu time

I am fortunate to have a Heathkit "Most accurate clock", which scans for
WWV or WWVH on up to 3 frequencies (5, 10, 15 MHz), locks onto the
strongest signal, and decodes the time code. It even has provisions
for propagation delay offset (in milliseconds) depending on how far the
user is from the transmitting station.
You just cannot believe how many guys try to convince me to sell it to
them, but, it ain't going anyplace. It is at least 25 years old,
probably closer to 30, but still runs great. All that is required is
the occasional touch-up of the PLL tuning, typically once every three or
four years. . Modern design could probably remove that minor issue.
That would be a good project for the likes of Elecraft. A truly useful
station accessory, and a good candidate for a kit to keep the "gotta
solder something" types happy. An updated design should be easy.
