UML Timing Diagram

We have some Batch Applications that run round the clock. After the developer releases this to the production environment a different team is responsible for the daily operations. The complexity of this application is such that it is difficult to convey the intricacies easily to that team. A UML timing diagram like the one shown below is one way of conveying the firing schedules to other teams.

This is not such a simple task though. Sometimes it is too intricate that several
training sessions are required but a diagram like this can be used as a ready reckoner.
