FlexSim is a tool to simulate processes all over the world. The current DateTime class is suited to compute time values to the base January 1st, 1601. But often we calculate time values to the base of current day, then the date part is not relevant. I would like to see a composed class WorldDateTime of components time of day, date and time zone. Each is a subset of properties and methods. The new time zone is a benefit for those, who works in different time zones with their models.
And it would be nice, if we get rid of two data classes dealing with similar attributes of time (Model, DateTime).
