This read-only DateAndTime, expressed in device local time, records when this configuration change request last finished running, resetting to the all-zero value '0000000000000000'H whenever the row is reactivated and remaining zero until the request completes. Admins use this timestamp to confirm exactly when a configuration push or image download actually finished, for change-management audit records. For instance, comparing this completion time against a maintenance window's end confirms the update finished on schedule.
