Timer Events are triggered by a defined timer. You can use the timer event in the Designer as boundary timer event and as intermediate timer event.

• Boundary: The timer is attached to an activity and works as a stopwatch and an alarm clock. When the execution reaches the activity, the timer is started. When the timer fires, for example after a defined interval, the activity is interrupted and the sequence flow exiting the timer is followed.
• Intermediate: You can also use the object as an intermediate catching event. In this case, the event is a separate process step. When the execution arrives at the event, a timer is started. When the timer fires, the sequence flow exiting the timer is followed.

To set the duration of the timer, the event should be trigged by a persisted property of type integer or datetime. You have two options to set the timeout in the attributes panel:

• Integer: Define the number of seconds the event has to wait.
• Datetime: Define the absolute datetime when the event should fire.
