The plugin now detects if the synchronization to the reference source is lost. Before, the plugin returned OK in this case. Now, WARN/CRIT is returned if synchronization is lost for a longer timeperiod. The default values are 30 and 60 minutes and can be configured with the option "Phases without synchronization" in the ruleset "State of NTP time synchronization". Note that "NTP time" services are affected as well by this ruleset.
