In UML modeling, a time trigger is an event that represents
the passage of a defined period of time or an absolute time. A transition
with a time trigger initiates when the time value is satisfied.
Before you can add a trigger to a transition,
you must have a state machine diagram open in the Modeling perspective.
To add a time trigger to a transition:
- Right-click a transition; then click .
- Type a name and press Enter.
