Some people call me "Tim" too. :-)

Try adding the following to your ZClass add method:

<dtml-call "REQUEST.set('ts', ZopeTime())">
<dtml-call "REQUEST.set('id', _.str(_.int(ts)))">

This will use the ZopeTime() as the id of your instance. I doubt you can add
them faster enough to get the same one twice. :-)
