There is no functional difference between those two data types. In order to avoid this duality, in the new data types for the revised ISO 13606 we have defined Duration as a specialization of Physical Quantity, with units constrained to units of time. The reasoning behind this decision is that a period of time should be always stored using the minimal unit of measurement. Then, we can transform it automatically to any desired format for visualization purposes.
