The Timetable is often modified by an adjective depicting a Period_of_iterations or a dependent noun expressing the Events of the Timetable. Note that this frame does not include the physical representation of a timetable. As of now this frame does not have an inheritance relationship, but in the future a *Mental_object frame will be developed from which Timetable will inherit. Changes to an employee's work schedule should generally be approved prior to the change actually occuring. The science students had very full timetables; these consisted mainly of lectures, with some lab sessions and problem classes or tutorials."@en .
