With the Timer Connector you can define when a workflow should run. A workflow will only be started if one is not already running.
You can choose between the following two types of timers:
Normal mode
Normal mode allows you to set specific times. E.g. every day at 8.00 AM.
Cron mode
The Cron Mode allows you to set specific recurring times with a Cron Expression. E.g. every second Monday the workflow is started.
