Yes, there are various timezone related changes, e.g.

http://zope3.pov.lt/trac/changeset/81213/Zope/trunk/lib/python/DateTime
http://zope3.pov.lt/trac/changeset/85830/Zope/trunk/lib/python/DateTime

It's hard to know whether this was an intended change or not, and if so, 
how to deal with the breakage in a way that's compatible with 2.10 and 2.12.

I blame Laurence. :-p
