/TIME_LIMIT={delta-time}
       /NOTIME_LIMIT (default)

          The /TIME_LIMIT qualifier specifies the maximum
          elapsed time allowed for a given defragmentation
          operation. If the time limit is exceeded, the
          defragmentation process is aborted.

          Specify time as a delta time. Refer to the VMS DCL
          Concepts Manual for more information on specifying
          times.

          For linked scripts, the time limit of the first
          script applies to the whole set. Time limits
          specified with successor scripts apply to these
          scripts only.

          If the time limit is set unreasonably low, the
          defragmentation process may not accomplish useful
          defragmentation.
