A bit of research shows that shapefile (well DBF) does not support
timestamp. You have the option of storing this in two parts (as a date
attribute and a time attribute) or storing it as a String as you are doing
above. It remains to be seen if our KML code can handle timestamps, to
experiment you will need to use a datastore that supports timestamps such
as PostGIS.
Let me try another line of inquiry .. searching the code.
* I could not find any examples of "when" in any of the test-data kml files
so it is safe to say this feature is not implemented.
* Reading the code there *is* a DateTimeTypeBinding, but it is not
implemented yet:
