Maybe you could use Zope's own DateTime, which can be
used in Scripts?

It's maybe not obvious, but implicit in the book is that the bindings
described for Scripts (container, context, etc.) apply only to Scripts,
and not for External Methods.

With External Methods, if the first argument to the function is
named "self", you can treat "self" as being equivalent to a python 
script's "context".

The request can be acquired as self.REQUEST.

The container of the external method... don't know. I never yet
had a case for an external method where I cared about the difference 
between context and container.
