Scenario 2: Infrequent execution I have a script based rule, where the Interval is set to every 4 hours and the sync time is set to 05:15. Sync time is based on a 24 hour clock, so 05:15 is 5:15am, local agent time. Lets say the monitored agent gets rebooted at 11:03 PM. The workflow will wait, to run on its defined interval, and execute based on its interval, that also must fall on 5:15 AM. Therefore, since the agent started up at 11:03 PM, the next possible interval on the 05:15 sync time would be 1:15 AM. This will be the first execution of the script, and then it will continue repeating every 4 hours, staying in sync with always having one of the executions running at 05:15.
