The command line utility to interefere with it is detailed in: man chronyc Typically I set /etc/chrony/chrony.conf and run it as a default service. Upon setting it up I run 'chronyc sources -v' a couple of times to make sure it is working as desired. For laptops which are not online 24-7 it is worth adding 'iburst' after the address of a time server to allow the clock to adjust fast at boot.

chrony on the "server" to sync from the Internet and systemd-timesyncd on the others to sync from the server.

After that, it just runs and does its work. If it helps, this is my chrony.conf file. root@fireball / # cat /etc/chrony/chrony.conf # Use public NTP servers from the pool.ntp.org project. #pool pool.ntp.org iburst ### SPECIFY YOUR NTP SERVERS # Most computers using chrony will send measurement requests to one or # more 'NTP servers'.

I found the manual here. It was the first hit on google for me. https://chrony.tuxfamily.org/documentation.html I'm no chrony expert by any measure. For me, the hardest part was finding the fastest servers. I think I use that mirrorselect tool, I think. Its been a while. Hope that helps. Dale :-) :-)
