Not sure what "undefined" means here but RFC 8011 defines date-time-at-completed thus:

5.3.14.7.  date-time-at-completed (dateTime|unknown|no-value)
   This RECOMMENDED attribute indicates the date and time at which the
   Job entered a Terminating State (’completed’, ’canceled’, or
   ’aborted’).
