Represents metadata about a service's support for querying features (see FeatureTable.queryFeatures(QueryParameters)) and requesting map images for ArcGISMapImageLayer based on time. It contains various time related information such as the map's time extent and the map's native time reference.
The default time window for the service to use for a time slider. Will return null if an error occurs or if the service doesn't define a default time window. If this value is null, then the time slider should create and use a time extent for an instant in time (start time = end time), if it is greater than 0 this value should be used as the difference between the start time and end time.
