Timing schedules are used for specifying when events are expected or requested to occur, and may also be used to represent the summary of a past or ongoing event.

    A Timing schedule can be a list of events and/or criteria for when the event happens, which can be expressed in a structured form and/or as a code. When both event and a repeating specification are provided, the list of events should be understood as an interpretation of the information in the repeat structure."/>
