Hi , I am using ROS Approximate Time synchronizer . I would like to know that , when the synchronizer fails to sync the messages( because of the Time stamps mismatch ) at a any particular instant, How can I find it and make actions accordingly at the same instant (Like Publishing a different message ) ?
