My undestanding is that it should be set by:

Here, the results of some commands:

warning, got bogus l2cap line.
That looks different: here's mine.
[john@HP_Box ~]$ netstat -a | grep ntp
udp 0 0 0.0.0.0:ntp 0.0.0.0:*
udp6 0 0 [::]:ntp [::]:*
[john@HP_Box ~]$ netstat -a | grep 323
udp 0 0 localhost:323 0.0.0.0:*
udp6 0 0 localhost:323 [::]:*
plus a few irrelevant responses.
but ...grep 123 shows nothing that looks relevant.
Quoting from the faq:
Perhaps you have a firewall set up in a way that blocks packets on port
323/udp. You need to amend the firewall configuration in this case.

In the output above....
'M'
This indicates the mode of the source. '^' means a server, '='
means a peer and '#' indicates a locally connected reference clock.
'S'
This column indicates the state of the sources. '*' indicates the
source to which 'chronyd' is currently synchronised. '+' indicates
acceptable sources which are combined with the selected source.
'-' indicates acceptable sources which are excluded by the
combining algorithm. '?' indicates sources to which connectivity
has been lost or whose packets don't pass all tests. 'x' indicates
a clock which 'chronyd' thinks is is a falseticker (i.e. its time
is inconsistent with a majority of other sources). '~' indicates a
source whose time appears to have too much variability. The '?'
condition is also shown at start-up, until at least 3 samples have
been gathered from it.

So, it seems your system is having problems to communicate with the remote servers.
Is this system at home or a workplace? Could be a firewall issue if it is in a workplace.

This is normal since you can't set the date/time if you're relying on NTP to do it.
