Why is this microtime showing up weird in PHP
<p>Why is this microtime showing up weird in PHP</p>

<pre><code>$start4 = microtime(true);
    // run some php code
$end4 = microtime(true);
print "Time4: ". ($end4 - $start4)."&lt;br /&gt;";
</code></pre>

<p>The above is showing:<br />
Time4: 2.69412994385E-5</p>

<p>Something with a more complex, longer running process shows up like this instead:<br />
Time1: 0.000292062759399</p>
