If it is always necessary to include a Constraint to make it clear when the Duty must be performed, does this need to be made explicit in the definition of a Duty in the Core Model

Yes - we updated the Duty description in the Model (See Section 2.5 - yellow text) so that we make no assumptions about when a Duty must/should be performed. It's obviously best to make these assumptions expressed explicit in the policy language.
