gm time command

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

To obtain time information for the execution of a command:

% gm time convert input.ppm -gaussian 0x2 output.ppm
convert input.ppm -gaussian 0x2 output.ppm    22.60s user 0.00s system 2354% cpu 0.960 total

Here is the interpretation of the above output:

• user - the total user time consumed.
• system - the total system time consumed.
• total - the total elapsed time consumed.

The time command reqires no options other than the gm command to execute.
