DateTime uses GMT rather than local time zone

[Dieter Maurer]

I understand the "DateTime" documentation as follows: if it gets a single string argument without time zope specification, it creates a "DateTime" in the local time zone. However:

>>> import DateTime
>>> DateTime.__file__
'/home/dieter/Z/zpython/lib/python2.6/site-packages/DateTime-2.12.2-py2.6.egg/DateTime/__init__.pyc'
>>> DateTime.DateTime('2010-05-20').timezone()
'GMT+0'
>>> DateTime.DateTime('2010/05/20').timezone()
'GMT+2'

Formerly (at least in the "DateTime" version that came with Zope 2.8), "DateTime('2010-05-20)", too, has returned a "DateTime" in the local time zone.
