Converts a string having the XML Schema Duration format into a DateTime object.

Duration may be expressed using all the parts of a DateTime type (from year to fractions of a second) and are, therefore, defined as a "six-dimensional space". As the relation between some of the date parts is not fixed (such as the number of days in a month), the order relationship between durations is only partial and the result of a comparison between two durations may be undetermined.
The lexical space of xsd:duration is the format defined by ISO 8601 under the form of PnYnMnDTnHnMnS. The capital letters are delimiters and can be omitted when the corresponding member is not used.

This example generates a DateTime object that corresponds to the duration of two days. This object can then be used to do time arithmetic, that is, adding and subtracting durations from dates.
You can find a xUML example of how to apply durations in section Arithmetic Operations.

set aDateTime = convertDurationToDateTime ("P2D");
