Date_views - Custom date field support (i.e. fields that are declared via coding)

Hey ppl! First of I want -of course- to thank all of you who helped build this incredible module, and also I apologize if this is any kind of duplicate.

Alright, I've been trying to use a custom date field within a view for more than a week now, and I think that I've found a correct way to do it.

first of, this is what my field looks like (within my module):

$my_table["date_field"] = array(
      'group' => $my_view_info['group'],
      'title' => t(' a date. '),
      'title short' => t(' date. '),
      'help' => t(' date. '),
      'field' => array(
        'field_name' => 'a date',
        'type' => 'datetime',
        'tz_handling' => 'none',
        'table' => 'my_table',
        'handler' => 'my_handler',
      ),
      'argument' => array(
        'table' => 'my_table',
        'handler' => 'views_handler_argument_date',
      ),
      'filter' => array(
        'table' => 'my_table',
        'handler' => 'views_handler_filter_date',
      ),
    );

What happens is that as you can see, I declare my own timezone and date type within this declaration, but the Field module does not support my field, since it wasn't declared within the normal mechanics of Drupal.

I noticed that in date_views/includes/date_views_fields.inc, some assumptions were made concerning that last fact:

// For Field module fields, get the date type.

[some code]

I made a patch that adds some conditions to this file, so that the handler is questionned if the Field module is not answering.

Tell me what you think, is this a good approach? Is there something missing?
