Chronus defines the following basic data types: (1) calendars, which specifies a set of granularities and the relationships between them; (2) granularities, which specify the resolution of a timestamp with a calendar; (3) datetimes, which are used to specify individual points in a timeline; (4) instants, which represent arbitrary points in a timeline; (5) periods, which represent segments of a timeline; and (6, 7) state and event tables, which extend standard relational tables with temporal information. All of theses types are described in the remainder of this FAQ.
