Time-stamped data in tabular form

timetable is a type of table that associates a time with each row. Like table, the timetable data type can store column-oriented data variables that have the same number of rows. All table functions work with timetables. In addition, timetables provide time-specific functions to align, combine, and perform calculations with one or more timetables. For more information, see Create Timetables or watch Managing Time-Stamped Tabular Data with Timetables.

To find and label events in a timetable, attach an event table to it. For more information, see eventtable.
