    93  <strong>time</strong> executes an arbitrary <strong>gm</strong> utility command
    94  (e.g. <strong>convert</strong>) and reports the user and elapsed time.  This
    95  provides way to measure command execution times similar to the Unix
    96  'time' command but in a portable and consistent way.
