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
