Together squllquake, we gave it a try. but failed. There is no public API. with java inspection you can get somewhere…. but not totally there.
If you need more control than the basics.. you have use an external build scheduler.
Something link this https://appstore.home.mendix.com/link/app/435/
Or build something based on http://www.quartz-scheduler.org/
There is a page in the Administration module that you can use to view your scheduled events. It displays the System.ScheduledEventInformation entity.
