There are several ways. One very simple method would be:

$Stime = time();
system("ls -l /");
$Etime = time();

print "It took ", $Etime-$Stime, " Seconds !\n";

That would give you precision upto a second. If you want better timing,
do:

use Benchmark;

$Stime = new Benchmark;
system("ls -l /");
$Etime = new Benchmark;

print "It took ", timestr(timediff($Etime, $Stime)), "\n";


hope that helps
