The most accurate Raspberry Pi atomic clock IN THE WORLD!

Will the fabric of space-time be split if I plug this highly-accurate Rubidium-oscillator-backed Time card into the Raspberry Pi?

Probably not, but we'll test the driver on the Pi, probably recompile a kernel or two, and learn about Linux PTP networking and GNSS-based timekeeping along the way!
