If I understand correctly, the trunk has had a BBB-incompatible change
to the semantics of the DateTime constructor:
In Zope 2.10.x (as well as 2.9x, 2.8x, and 2.7x):
>>> from DateTime.DateTime import DateTime
>>> DateTime('2006/01/01')._tz
'US/Eastern'
>>> DateTime('2006/01/01 UTC')._tz
'Universal'
>>> DateTime('2006-01-01')._tz
'GMT+0'
On the trunk:
>>> from DateTime.DateTime import DateTime
>>> DateTime('2006/01/01')
DateTime('2006/01/01')
>>> DateTime('2006/01/01')._tz
'US/Eastern'
>>> DateTime('2006/01/01 UTC')._tz
'UTC'
>>> DateTime('2006-01-01')._tz
'US/Eastern'
I strongly disagreed with the argument for that change
(http://www.zope.org/Collectors/Zope/2109), because it broke the
semantics of the class, based on long-established use in Zope: datetime
strings which used ISO notation, but provided no explicit timezone, were
assigned 'GMT+0' as the timezone.
The trunk should be reverted to preserve the old behavior, which may be
relied on by third-party applications.
