Time frames with duration i.e. Financial Year, as below, allow precise attachment of reports that have a duration relationship i.e. set of financial statements, profit loss report, trial balance report or general ledger report amongst others.

Documents may have an Instant relationship i.e. a relationship with a point in time. Such documents will include legal documents with dates signed and balance sheets with as at time point associations. Regulatory notices should be referenced primarily by duration where the notice is specific to a particular duration but should be referenced by instant where the notice is not specifically related to duration. An Activity Statement Regulatory Notice would be of type - Duration, since the notice will relate specifically to a from to date rage.
