[fedora-arm] Real time clock on Udoo Neo : how to configure ?

[Ken Harris]

People :

I'm trying to get the RTC working on a Udoo Neo.

I installed a battery and set the RTC and it keeps running (a bit
fast) while powered off, but on power up the system clock is several
months off (11 may).

It's not clear how configure this. Should I use timedatectl (in
systemd) or timedatex (https://github.com/mlichvar/timedatex) or
something else ?

Thanks,
Ken

It should be relatively automated.

How many devices in /dev/rtc* sometimes I've seen there's two RTCs on
devices, the one of the SoC which isn't battery backed, and then an
addon one which is, if there's two and the SoC one is rtc0 it often
uses that as the canonical source and it causes issues.
