How to change default timestamp that PHP uses for logging to file?
<p>In the php.ini:</p>

<pre><code>error_log = php_errors.log
</code></pre>

<p>So all <code>error_log()</code> calls go into the file <code>php_errors.log</code>, every line is prepended by timestamp like <code>[17-Jan-2012 18:05:04]</code>.</p>

<p>Is it possible to modify that timestamp? I need to display milli/microseconds as well as seconds and don't know how to do that using standard config options.</p>
