[time-nuts] Raspberry Pi NTP server

Thanks Hal

I could try and get a wire onto the GPIO, with a lot of work...

FT232R is a USB chip.  Timing over USB is "interesting".  Do you know about hanging bridges?

Can you get a wire in to the GPIO pin the HAT used?  That would be an interesting experiment.

There may be a parameter you can tweak, but I can't think of the name right now.
