Manual edit doesn't work with translated sites

The check for $node->op on line 124 doesn't account for translations

  if ($node->op == 'Save' && $node->published) {
    $node->published = strtotime($node->published);
  }

On my site the $node->op == 'Indsend' - so an easy fix could be to check for $node->op == t('Save')

But I maybe a better solution could be to check for $node->form_id == $node->type.'_node_form' instead
