Duration Description
From Open Risk Manual
Definition
Duration Description. The description of a Duration in terms of numbers of days, hours, years etc.
The duration of an interval (or temporal sequence) can have many different descriptions. An interval can be 1 day 2 hours, or 26 hours, or 1560 minutes, and so on. It is useful to be able to talk about these descriptions in a convenient way as independent objects, and to talk about their equivalences. The extent of an interval can be given using multiple duration descriptions or individual durations (e.g., 2 days, 48 hours) , but these must all describe the same amount of time.
