Only supported for ArcGIS Image Server from version 10.0 onward. The layer/table must also support querying and exporting maps based on time.

The TimeExtent Property provides metadata about the layer’s service. If temporal information is available (meaning it is not null/Nothing) for the geographic data in the layer’s service, then developers can take advantage of using the Map.TimeExtent Property to display snapshots of the temporal data that cover a specified time period (aka. TimeExtent). Once common use case is to bind a TimeSlider Control with the a Map Control to provide an interactive user experience of showing how geographic temporal data changes over time.

Several examples where a FeatureLayer with TimeExtent information can be used to display snapshots of temporal geographic data can be found in the SDK documentation for the TemporalRenderer Class, TemporalRenderer.LatestObservationRenderer Property, TemporalRenderer.ObservationRenderer Property, TemporalRenderer.TrackRenderer Property, RampInterpolator Class, and TimeClassBreaksAger Class.
