[Zope] ImportError: import unauthorized

That particular module is not restricted for Python Scripts. 
Why? Very complicated.

If you want to use modules that are forbidden for Python Scripts, let an 
External Method do the crude job and try to keep as much code as possible in 
the script. 

Example:

## External Method /Extensions/careful_strftime.py ##
import time.strftime, time.strptime
def careful_strftime(self, *args):
  return strftime(args)

## Zope object careful_strftime ##
Id: carefule_strftime
Module: careful_strftime
Function: careful_strftime

## Python Script ##
BDate = context.careful_strftime("%d.%m.%Y", xxx)


You must obviously do the same to strptime().

It is a good idea to keep a py file in Extensions filled with little hacks 
like this.

Alternativly, look into the XXXPythonScript product on zope.org
