I18n support for validates_date_time

This simple fix uses the fact, that if the second argument to the ‘add’ method is a symbol, then a generate_message is called, which does all the voodoo of Rails 2.2 I18n.
I tried to contact the original author to no avail, therefore I’ll post it here, hoping that if anyone needs it, it’ll surface on a Google search.
The fix itself is quite simple:

I’ve a fork of the git-svn mirror here:
http://github.com/romanbsd/validates_date_time/tree/master

Then, for using it, you’ll just need to have the following path in your locale yml files (for example):

  activerecord:
    errors:
      models:
        user:
          attributes:
            birth_date:
              before: 'is wrong'
              after: 'is wrong'
