Notice how chronyd is trying to use IPv6 addresses, when my home doesn't have IPv6. The network is autoconfigured with DHCP (network manager) from the ISP provided and configured router.

What should I look at? The system is with default configurations, installed hours ago.
First question - is there a problem? I don't use chrony myself, but it looks like it selected two IPv4 sources, which sounds good. IIUC, the "source replaced with" message simply means that an unreachable server was swapped out for another one (not necessarily more reachable).
Well, I don't know if there is a problem. Hard to see if the clock is off or not. To me it looks like if first tries an IPv4 address, then one minute later it selects another, I guess because the first one doesn't work. After 3 minutes it selects another. This doesn't look to me like it is using 3 ipv4 sources in parallel, but maybe I'm reading wrong.
There must be a query tool for that - like ntpq - to show which sources, stratum, availability etc.
Ah yes, google tells me: "chronyc tracking".
From the Fedora projects sysadmin guide :-)
It is the first time I actually "use" chrony, and it is not my main goal on that machine - I got sidetracked because the entries are visible in the log ;-) Thanks for spotting that.
