That's exactly what we do with GPS tracks; if you upload them, the timestamp is not changed. If you create nodes/ways/relations however, that is a separate process (and not always associated with a GPS track - think tracing from imagery). When creating an object, you could be looking at any number of GPS tracks covering any length of time. It is not possible to deduce a sensible timestamp in a general fashion. (If some later edits an object while looking at an older GPS tracks, would the timestamp then have to be moved further into the past?) Because of all these complexities, we simply use the timestamp when the object entered the OSM database.
