# TimeIntervalCollectionProperty

#### new TimeIntervalCollectionProperty()

  A `Property` which is defined by a `TimeIntervalCollection`, where the data property of each `TimeInterval` represents the value at time.

  ##### Example:

      //Create a Cartesian2 interval property which contains data on August 1st, 2012
      //and uses a different value every 6 hours.
      var composite = new Cesium.TimeIntervalCollectionProperty();
      composite.intervals.addInterval(Cesium.TimeInterval.fromIso8601({
          iso8601 : '2012-08-01T00:00:00.00Z/2012-08-01T06:00:00.00Z',
          isStartIncluded : true,
          isStopIncluded : false,
          data : new Cesium.Cartesian2(2.0, 3.4)
      }));
      composite.intervals.addInterval(Cesium.TimeInterval.fromIso8601({
          iso8601 : '2012-08-01T06:00:00.00Z/2012-08-01T12:00:00.00Z',
          isStartIncluded : true,
          isStopIncluded : false,
          data : new Cesium.Cartesian2(12.0, 2.7)
      }));
      composite.intervals.addInterval(Cesium.TimeInterval.fromIso8601({
          iso8601 : '2012-08-01T12:00:00.00Z/2012-08-01T18:00:00.00Z',
          isStartIncluded : true,
          isStopIncluded : false,
          data : new Cesium.Cartesian2(5.0, 12.4)
      }));
      composite.intervals.addInterval(Cesium.TimeInterval.fromIso8601({
          iso8601 : '2012-08-01T18:00:00.00Z/2012-08-02T00:00:00.00Z',
          isStartIncluded : true,
          isStopIncluded : true,
          data : new Cesium.Cartesian2(85.0, 4.1)
      }));
