TPO Pit session and ON Times

For non-Cash settled futures like CL, GC or Treasuries, if somebody can please advise what times you are using for RTH (Pit) session and ON sessions? I found the following RTH times per CME - but it seems off to me that ON sessions would be the remaining times. Thanks in Advance.
