I think consensus here is that the DateTIme stuff has BBB contracts
which are literally unbreakable:

 - millions of pickles are out there in ZODB land which will barf if
   DateTime doesn't preserve existing semantics.

 - Bunches of third-party application code uses the DateTime API, in
   particular the DWIMish constructor.

I think your change (using pytz to handle timezones, with fallback to
the older code) is a sensible compromise.
