Mine shows:

   Universal time: Wed 2024-03-06 17:09:44 UTC
         RTC time: Wed 2024-03-06 17:20:53
        Time zone: America/New_York (EST, -0500)
  Network time on: yes
NTP synchronized: no
  RTC in local TZ: no

How do I get the RTC to agree with the right time?


"hwclock -w" to copy the system clock to the hardware clock (RTC).  This
should also be done during shutdown, but it doesn't hurt to do it now.

Systemd has that feature. Turn in on with

     sudo timedatectl set-ntp true


But *don't* do that if you're using some other NTP program instead of
systemd-timesyncd.  Unfortunately, timedatectl does not know about other
NTP programs, and won't report which one you're using.  You'll have
to find that out yourself
Are you saying that both chrony and ntpsec, which are fully ntp client/server ack the docs are worthless to timedatectl?
I have a quite good 3d printer, but its running armbian buster, its out of synch by days despite ntpsec running and I can see it access my own level 2 server but the timedate never synchronizes. I need to know how to setup timedatectl to slam the ntp time into the system clock on first access at bootup. That would fix a lot of bogus times reported by fluidd, the printers web based gui front end. 

Thanks Greg. Take care & stay well.
