### 3.2.174 times

    times

This function returns a four-element list giving the user and system CPU times, in seconds (possibly fractional), for this process and the children of this process.

    ($user, $system, $cuser, $csystem) = times;

For example, to time the execution speed of a section of Perl code:

    $start = (times)[0];
    ...
    $end = (times)[0];
    printf "that took %.2f CPU seconds\n", $end - $start;
