i was looking at the php help page and found this script below, apparently its supposed to be a timer.. but i did a echo of microtime and found a bunch of gibberish float values. whats its purpose?? thanks

Code:

<?php
$time_start = microtime(true);

// Sleep for a while
usleep(100);

$time_end = microtime(true);
$time = $time_end - $time_start;

echo "Did nothing in $time seconds\n";
?>
