Create an IfxTimeSpan

In constructors that accept values for multiple time units, the values do not have to make sense with each other the way that they do in the constructors for an IfxDateTime. The values for one or more of the time units can be negative. The value of the created IfxTimeSpan is the sum of the time represented by each of the units.

Example: If you create an IfxTimeSpan using values of 50 days, 27 hours, and -5 minutes. The resulting IfxTimeSpan will be set to 51 days, 2 hours, and 55 minutes.
