  Display the FeatureLayer in myMap2 that has a TemporalRenderer applied:
          
  Add an ArcGISTiledMapsServiceLayer as a background to the map. The ArcGISTiledMapsServiceLayer 
  layer is first Layer added to the Map's Layers Collection and is drawn on the bottom. A FeatureLayer 
  is then added to the map and draws on top of the background layer.
          
  Set the Map2 Extent to zoom to the North and South America.
          
  Setting the Map's TimeExtent acts like a Where clause in that only those features/records that fall
  within the set TimeExtent will then be shown. In the case of this example the TimeExtent for the 
  earthquakes is shortened to a smaller temporal window to display the various rendering effects clearly.
          
  Manually setting the TimeExtent of the Map2. Could have bound to a TimeSlider for more interactiveness.

    returned per FeatureLayer. In ArcGIS Server 10 the default is 1000. This setting is configurable 
    per map service using ArcCatalog or ArcGIS Server Manager (on the Parameters tab). This Where
    clause only displays earthquakes where one or more deaths have occurred.
