/AFTER={time}
       /AFTER={current_time} (default)
       /NOAFTER

          The /AFTER qualifier keeps the script from executing
          until after the specified time.

          You can specify time as either an absolute time or
          as a combination of absolute and delta times. For
          complete information on specifying time values, see
          the VMS DCL Concepts Manual.

          The /AFTER qualifier has three states. It can be
          specified with a valid time, it can be omitted from
          the command line, or it can be negated (/NOAFTER). If
          /AFTER is specified with a valid time, the script is
          scheduled to execute after that time. If the /AFTER
          qualifier is omitted, the defragmentation software
          processes the command as if the /AFTER qualifier
          were specified with the current time. If /NOAFTER
          is specified, no starting time is associated with
          the script being defined. The /NOAFTER qualifier
          allows you to define a script without scheduling it
          to execute. To subsequently start the script, use the
          START subcommand.
