Alas. In concept, that is extremely interesting. But a bit too
bare-metal for me; first I'd have to recruit help to design and build
it into something one of my computers can talk to.

OTOH, I have written successful I2C code; if something like this
hardware were a Raspberry Pi HAT I'd have bought one before I finished
typing this reply and probably have a test system up in 24 hours. So
it's close.  Real close.  Relevant link:


It would be delightful to add a WWVB radio version of the build
to that document.
