I am not surprised that you are formatting a database result.
I am surprised that in the byte code there is an "import time"
(or an import at all).


I tried to reproduce your problem and failed:

bin/zopectl debug
>>> from datetime import datetime
>>> from AccessControl import allow_type
>>> allow_type(datetime)
>>> from Products.PythonScripts.PythonScript import PythonScript
>>> ps=PythonScript('t')
>>> ps.write('''##parameters=dt
... return dt.strftime('%d.%m.%Y')
... ''')
>>> dt=datetime(2006,12,1,20,0,0)
>>> ps.__of__(app)(dt)
'01.12.2006'

And this is the Python Script's code:

>>> f=ps._v_f
>>> from dis import dis
>>> dis(f.func_code)
  1           0 LOAD_GLOBAL              0 (_getattr_)
              3 LOAD_FAST                0 (dt)
              6 LOAD_CONST               1 ('strftime')
              9 CALL_FUNCTION            2
             12 LOAD_CONST               2 ('%d.%m.%Y')
             15 CALL_FUNCTION            1
             18 RETURN_VALUE
             19 LOAD_CONST               0 (None)
             22 RETURN_VALUE



I am using Zope 2.8.1 with Python 2.4.1.
