Used in the following classes as alternative to the datatype property "s4ee:timestamp" in case one wants to describe the timestamp using duration (instead of xsd:date time):
- In the Sensing class is the creation time of the sensingData instance.
- In the Messaging class is the point in time in which the message was generated.
- In the Measurement class is the time of creation of a value element (measured, calculated, ...). Some sensors and communications technologies may already provide this information natively. In other cases the technology interface may set timestamp to the time of creation of a measurementData instance.
