As not mentioned, if used with invalid unit value, it uses default one:



<?php

        $stopWatch = new HRTime\StopWatch();

        $stopWatch->start();

        for($i=0; $i<10000000; $i++);

        $stopWatch->stop();

        echo $stopWatch->getElapsedTime(-1) . ' - ' . 

        $stopWatch->getElapsedTime(0) . ' - ' . 

        $stopWatch->getElapsedTime(1) . ' - ' . 

        $stopWatch->getElapsedTime(2) . ' - ' . 

        $stopWatch->getElapsedTime(3) . ' - ' . 

        $stopWatch->getElapsedTime(4);

?>

Outputs soething like:

0.11936771 - 0.11936771 - 119.36771 - 119367.71 - 119367710 - 0.11936771
