Actually I've been playing around more and there's some cases left out of the driver. I hacked it to put them in and it works much better now. (Was giving Bad Timestamp exceptions). I've attached the hacked / fixed ResultSet.java file as I have no CVS access, would some kind soul with access patch it? I've marked my changes clearly with comments in the getTimestamp() method. Hope this helps!
