Chrony's default minpoll and maxpoll values are 64 seconds and 1024 seconds. In standard situations (good internet connection, low error etc) the interval between polls should stick near the max value (1024 seconds). (see https://chrony-project.org/examples.html#_client_using_public_servers)

Beacuse of that, the default WARN alert is now set to 1025 seconds.
