[Zope] date handling and MySQL

Hello, I'm looking for some examples of date handling with Zope and MySQL. for example, a DATETIME column under MySQL doesn't like the value from PrincipiaTime. Also, I'd like to input and display dates in french format (dd/mm/yyyy) instead of english format (yyyy/mm/dd), given the fact that mysql stores the date If someone could send me some example of their (python/dtml) code... Many thanks. Jephte CLAIN, Service Informatique CHSR
