What happens if the network connection is dropped without using chronycs offline command first?
In this case chronyd will keep trying to access the server(s) that it thinks are online. Eventually it will decide that they are unreachable and no longer consider itself synchronised to them. If you have other computers on your LAN accessing the computer that is affected this way, they too will become ‘unsynchronised’, unless you have the ‘local’ directive set up on the master computer. The ‘auto_offline’ option to the ‘server’ entry in the chrony.conf file may be useful to avoid this situation.
