Well, I want something maybe in between. Currently I think I have that: I
have a RPi disciplined to the Adafruit Ultimate GPS HAT via chrony (PPS
etc.). This works well.

So I think this is what I'm talking about. I want something a little bit
more esoteric than a GPS 1PPS. Can you explain a bit about these
prepackaged Rubidium standards? Upside/downside etc. Do I have to
maintain/check these black boxes?

Again, take over the world. Sorry for not being upfront about that. That
would have made things A LOT clearer.
So I guess: How can I get a simple Rubidium standard that outputs a
reference frequency as a discipline to say ntpd or chrony.
Btw, I'm a noob. Please be gentle.
