Time extent is a two element array that can represent time extent or time instant. The two elements represent values for start and end time. The number represents the number of milliseconds since epoch (January 1, 1970) in UTC. A null as start indicates all inclusive since the beginning of time and a null as end value indicates indefinite time with no end. Time instant can be represented by setting same value for both start and end.
