8.5.3.14 IfcWorkTime
8.5.3.14.1 Semantic definition
IfcWorkTime defines time periods that are used by IfcWorkCalendar for either describing working times or non-working exception times. Besides start and finish dates, a set of time periods can be given by various types of recurrence patterns.
A work time should have a meaningful name that describes the time periods (for example, working week, holiday name). Non-recurring time periods should have a start date (IfcWorkTime.Start) and a finish date (IfcWorkTime.Finish). In that case it is assumed that the time period begins at 0:00 on the start date and ends at 24:00 on the finish date.
The start and finish date is optional if a recurrence pattern is given (IfcWorkTime.RecurrencePattern). They then restrict never-ending recurrence patterns.
