There's a lot of interesting stuff in the time-nut world. There's a fun mailing list at https://time-nuts.febo.narkive.com/ and Jeff Geerling has been doing a lot of stuff with clocks lately on YouTube. An interesting intro project is to set up a GPSDO and track the long-term aging of an OXCO or Rubidium standard (many of which are surplused out of telecom applications for somewhat reasonable prices on eBay).

Is this going around in other places today, or does posting something to HN qualify as "hype"?
It was just the correct time.
I mean, time really is a tough nut to crack.
When is it time to run a world class time reference in your basement?
For time nuts, it's always time...
