new Cesium.TimeIntervalCollectionProperty()
engine/Source/DataSources/TimeIntervalCollectionProperty.js 43

A Property which is defined by a TimeIntervalCollection, where the data property of each TimeInterval represents the value at time.
使用示例:
//Create a Cartesian2 interval property which contains data on August 1st, 2012
//and uses a different value every 6 hours.
const 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)
}));
