Hello dear Justin,
I am fond of the mapbuilder time series demo. It can play layers like playing a movie.The openlayers have not this demo only a wmst(wms+time).Do you know how the data organized in geoserver can support the time series WMS? The code in
openlayers 1.4 wmst demo is as follows.Thank you for your help all the time.By the way,why do you replace mapbuilder demo with openlayers? I think most mapbuilder functions the openlayers have not.
Best Wishes for you!
Sincerely yours,
Yang

Hi,
Time is not really supported directly in GeoServer. Although Alex
recently contributed a patch for time with NetCDF. The only solution
(from what I have read) is to use a filter in a wms request which
references a timestamp in your data. Although this wont work with a
MapBuilder time series map.
Others can comment but I think one of the big reasons for switching to
openlayers was simplicity. Setting up the map builder demo on the fly
was a bit of a mess. MapBuilder does provide some functionality that
OpenLayers does not but we do not really use any of it. And since the
two code bases are headed for a merge it seemed like a reasonable switch.
