This is right. But datetime classes are difficult to handle in cpyext, because they are pure-python classes. They don't have a specific "TypeDef", and cpyext ties the C structs to those typedefs. See sliceobject.py for a simple example of filling the C struct; I don't know how to do this for datetime. -- Amaury Forgeot d'Arc
