Can chrony be driven from broadcast NTP servers?
No. I remember looking at how they worked when I was first writing chrony. Since the ‘target market’ then was dial-up systems, broadcast packets were not relevant so I didn’t bother working out how to deal with the complexities of doing the delay estimation. I no longer have root access to a LAN environment to develop and test broadcast server support. Neither have I the time to work on this. I would be very happy to accept a patch from anyone who can develop, test and debug the necessary changes! 12.2. Can chronyd transmit broadcast NTP packets (e.g. to synchronise other computers on a private LAN)? Yes. Starting from version 1.17, chrony has this capability. 12.3. Can chrony keep the system clock a fixed offset away from real time? I have not experimented much, but I don’t believe this would be possible as the program currently stands. 12.4. What happens if the network connection is dropped without using chronyc’s ‘offline’ command first? In this case chronyd will keep trying to acce
