Perhaps just some additional documentation about Joda-Time  
interacting with date instances that are, as you put it, without a  
timezone.  Understanding this was crucial for me to integrate Joda- 
Time into an application that already has its fair share of  
calendaring code, and now that it's working perhaps I can make the  
case for refactoring more of our application to use Joda-Time!

Thank you for the help.
