time-interval

This is the class of time-interval objects, which (when fully specified) have a start, an end, a duration, and a number of recurrences. time-intervals are created with the time-interval function.

Time intervals have four slots:

• start, with reader time-interval-start.
• end, with reader time-interval-end.
• duration, with reader time-interval-duration.
• recurrences, with reader time-interval-recurrences.

See date-time.htm for information on support in Allegro CL for parsing and generating time expressions using the ISO 8601 standard.
