4.2.281 Interval_of_time

An Interval_of_time specifies a period of time.

The data associated with an Interval_of_time are the following:

4.2.281.1 end_definition

The end_definition defines the end of the Interval_of_time, either by referring to a bound, or specifying the extend of the Interval_of_time by a Duration. If the end_definition refers to an Event_reference or Date_time, this particular bound of the resulting interval is excluded from it.

See interval_of_time to date_time, interval_of_time to duration, and interval_of_time to event_reference for the application assertions.

There shall be exactly one object that defines the end_definition for an Interval_of_time.

4.2.281.2 start_definition

The start_definition defines the beginning of the Interval_of_time. The bound specified by the start_definition is included in the resulting interval.

See interval_of_time to date_time and interval_of_time to event_reference for the application assertions.

There shall be exactly one object that defines the start_definition for an Interval_of_time.
