What kind of data is stored in the kml?
We recently had an issue that it may not contain points *and* lines 
together. Ogr2ogr expects either points, lines, or polygons, but not all 
together. Maybe your time data is notr recognized by teh ogr driver as well.

Perhaps you can convert it to GPX format with gpsbabel. The gpx importer 
in Qgis allows data with timestamp.

HTH,
