UML22 — Section: 13 SimpleTime

What the time model needs is the concept of an optional time reference that can be attached to a time observation (e.g. to model a spacecraft/ground station situation). The MARTE profile has done some excellent work on this and it should be taken into account when resolving the issue

Resolution: The simple time model is just that: a very simple model to attach time specifications to observations, for example. When a more sophisticated handling of time is required, profiles such as the MARTE profile should be used. The proposal is not to attempt to enhance the simple time model but only fix problems with that model. Disposition: Closed, no change
