Since the update to NTPv4, when the clock is in the synchronised state and the clock updates stop (e.g. sources become unreachable), it doesn't switch to the unsynchronised state and the local reference is never activate. This can be a problem for clients that rely on the server to always have root distance below some value (e.g. chronyd's maxdistance). Add a timer that will activate the local reference when the root distance reaches a specified threshold. It can be configured with the distance option in the local directive (by default 1.0 second).
