I would really like to deprecate datetimeutils. It is just evil. However, we 
cannot remove it until someone adds TZ support to zope.i18n.

The right way to do it would be to import a timezone package based on 
datetime, and implement the necessary lines in zope.i18n.format (around line 
105 for parsing and lines 575-586 for formatting). You can see that the code 
should not be too hard as long as the timezone can give us the following 
representations: "+000", "+00:00", "UTC" and "Greenwich Time". Of course, 
there needs to be a function that can give us the timezone for any of the 
given strings.
