function _tracker_calculate_changed

Picks the most recent timestamp between node changed and the last comment.

@todo Check if we should introduce 'language context' here, because the callers may need different timestamps depending on the users' language?

Parameters

\Drupal\node\NodeInterface $node: The node entity.

Return value

int The node changed timestamp, or most recent comment timestamp, whichever is the greatest.

function _tracker_calculate_changed($node) {
    $changed = $node->getChangedTime();
    $latest_comment = \Drupal::service('comment.statistics')->read([
        $node,
    ], 'node', FALSE);
    if ($latest_comment && $latest_comment->last_comment_timestamp > $changed) {
        $changed = $latest_comment->last_comment_timestamp;
    }
    return $changed;
