Created a new job. Changed the schedule for the existing job to every two minutes, knowing that it takes longer. It behaves as expected, checking against the start and stop times in the task logs, I see that the job takes about 5 minutes to complete and the the next run is scheduled within the same minute as the previous stops. Though the start / stop time is shown only with minute precision here (seconds are always 00).
