Hi! Thanks for the reply. So I suppose when I make a WMS request with TIME Mapserver applies the filter behind the scenes, finding which feature in my tile_index.shp represents the correct time and then processes the raster pointed to by that feature? So if I want to implement the same kind of thing with mapscript I'd have to write the filter myself?
The reason I am interested in doing this is to extend temporal functionality to ka-map. I may end up abandoning that approach and moving to a javascript WMS client (like OpenLayers of MapBuilder) instead. Thanks for your help.
