docs: def attach_subdivision(times):
      """
      Manual assignment of a (stopped) times object as a subdivision of running
      timer.  Use cases are expected to be very limited (mainly provided as a
      one-Times variant of attach_par_subdivision).
  
      Notes:
          As with any subdivision, the interval in the receiving timer is assumed to
          totally subsume the time accumulated within the attached object--the total
          in the receiver is not adjusted!
  
      Args:
          times (Times): Individual Times data object.
  
      Raises:
          TypeError: If times not a Times data object.
