Field handler for the gallery's updated time.

Code

function render($values) {

    ->get_cover_node_nid($values);

  // If there is no node (ie gallery empty), suppress the label.
  // Because this is called for each row, but $this->options['label'] applies
  // to everything, we have to muck about and stash the original, user-set
  // value so we can restore it when needed.
  // @todo: views 6.x-2.7 will make all the label stuff superfluous.
