I'd be interested in installing these bits:
https://github.com/ddrown/chrony-graph - graphs (I have a ntpd port of
this already, not yet published)
- example output: https://dan.drown.org/rpi/latest/
https://github.com/ddrown/ntp-www - realtime status (also have an
unpublished ntpd port)
- an example of this on a machine without a gps module is here:
https://clock.drown.org/
I've also been working on CEP50 measurements of various GPS modules.
That might be useful as well.
- example graphs from that: https://dan.drown.org/gps/distance.png +
