While there is lot of discussion on the zope3 list how to solve the 
problem, we
have not found a suitable solution for Zope 2 which is IMO very important.

What about the following idea:

 - the DateTime constructor gets a new keyword argument "datefmt" with two
   possible values "us" (default) and "european"

 - "european" would force the parser to treat the date with day before month
   before year

 - "us" would not change the default behaviour for compatibility reasons

 - a new env variable DATETIME_FORMAT would allow to specify this
   behaviour for the complete Zope instance

 - the ZPUblishers notations for date types should be extended to:

   "field:date" for US dates and

   "field:date_european" for european dateformat (or a notation like
   like "field:date:european" )

Cheers,
Andreas
