Broken Views handler

..it's a bit tricky because there are two columns in database and both should appear in the views result objects.

Views handler will always be broken when no table from cck hook_field_settings(.., "views data",..) returned!
CCK: cck/includes/views/content.views.inc:119 - This is where CCK collects data for views; and this is where hook_field_settings("views data") gets invoked!

function content_views_data() {
  $data = array();
  foreach (content_fields() as $field) {
    $module = $field['module'];
    $result = module_invoke($module, 'field_settings', 'views data', $field);
    if (empty($result)) {
      $result = content_views_field_views_data($field);
    }
    if (is_array($result)) {
      $data = array_merge($data, $result);
    }
  }
  return $data;
}

Views: views/views.module:573 - This is where views handler will be set to broken_handler if there's nothing useful returned by CCK:

function views_get_handler($table, $field, $key) {
  $data = views_fetch_data($table);
  if (isset($data[$field][$key])) {
    // Set up a default handler:
    if (empty($data[$field][$key]['handler'])) {
      $data[$field][$key]['handler'] = 'views_handler_' . $key;
    }
    return _views_prepare_handler($data[$field][$key], $data, $field);
  }
  // DEBUG -- identify missing handlers
  vpr("Missing handler: $table $field $key");
  $broken = array(
    'title' => t('Broken handler @table.@field', array('@table' => $table, '@field' => $field)),
    'handler' => 'views_handler_' . $key . '_broken',
    'table' => $table,
    'field' => $field,
  );
  return _views_create_handler($broken);
}

..this function calls amongst others _views_fetch_data in views/includes/cache.inc:27:

/**
 * Fetch Views' data from the cache
 */
function _views_fetch_data($table = NULL) {
  static $cache = NULL;
  if (!isset($cache)) {
...
    if (empty($cache)) {
      $cache = module_invoke_all('views_data');
      foreach (module_implements('views_data_alter') as $module) {
        $function = $module . '_views_data_alter';
        $function($cache);
      }

      views_cache_set('views_data', $cache, TRUE);
    }
...

What the patch does:
Now duration module implements hook_field_settings(.."views data"..) with a modified copy of the CCK-version in function content_views_field_views_data in cck/includes/views/content.views.inc:135.
The ISO field now only implements the basics. So views filters,sorts and arguments were omitted by me. This code has to be adapted for the final use :)
Patch attached.
