or other nonstandard base units, and times can be entered using exact day counts. Modelica as a language is constantly evolving, so hopefully, some of the innovations this library introduces might find their way into the mainstream. A tentative proposal has been made to the language group.Tutorial.UnitsInBusinessSimulations
