What Philip said :)

Note that i18n:target is broken ... See
http://zope.org/Collectors/Zope/1114 for a potential solution.

If you try to use the currency functionality, you may also run into
problems ... In that case, see this post:

This is quite outdated. It doesn't surprise me you're getting an error

Like Jean-Francois said, zope.i18n.locales has some good support for
formatting datetime values (the Python variant, not Zope's DateTime
variant). In Zope 3, this functionality is available through
request.locale. In Zope 2, you will have to create the locale object
yourself like so:

  from zope.i18n.interfaces import IUserPreferredLanguages
  from zope.i18n.locales import locales

  languages = IUserPreferredLanguages(request)
  langs = languages.getPreferredLanguages()
  if langs:
      parts = (langs[0].split('-') + [None, None])[:3]
      parts = (None, None, None)

  locale = locales.getLocale(*parts)

Then you can format datetimes such as the 'modified' variable in the
below example like so:

   <p i18n:translate="" tal:condition="modified"
     Last modified on
     <span i18n:name="modified_date"
           tal:replace="python:formatter.format(modified)" />

My book explains all of this in detail. I suggest picking up a copy :)
