Code

function edit_limit_link_alter(&$links, $node, $comment = NULL) {

    // Allow edit links if the edit count hasn't been reached yet.
    // TODO: Complete this functionality.

    }

    // Allow edit links if there is enough time left based on the system variable edit_limit_comment_time.
    // We don't have to do much user access checking, since this link will only exist if the user passed
    // the comment_access() check for this given comment.
    if (!user_access('bypass edit limit') && variable_get('edit_limit_comment_time_enabled', FALSE)) {
      $time_limit = $comment->timestamp + intval(variable_get('edit_limit_comment_time', EDIT_LIMIT_COMMENT_TIME));

        unset($links['comment_edit']);
      }
      else {

        // Add the javascript that will handle the countdown.
        drupal_add_js(drupal_get_path('module', 'edit_limit') . '/edit_limit.js');

        // Modify the link to add the remaining seconds (only users that can't pass 'bypass edit limit' get this far).
        $links['comment_edit']['title'] .= ' (' . ($time_limit - time()) . ' seconds left)';
