Description:
------------
When you run the test script, the second outpot is parsed false. It returns the date minus one day. Maybe this error occures with other strings also.

Test script:
---------------
<?php

$dt = new DateTime('-1999-06-22 00:00:00');
echo "\nThis should be -1999-06-22 00:00:00 -> " . $dt->format('Y-m-d H:i:s');

$dt = new DateTime('-1916-06-22 00:00:00');
echo "\nThis should be -1916-06-22 00:00:00 -> " . $dt->format('Y-m-d H:i:s');

Expected result:
----------------
This should be -1999-06-22 00:00:00 -> -1999-06-22 00:00:00
This should be -1916-06-22 00:00:00 -> -1916-06-22 00:00:00

Actual result:
--------------
This should be -1999-06-22 00:00:00 -> -1999-06-22 00:00:00
This should be -1916-06-22 00:00:00 -> -1916-06-21 00:00:00

I have a fix and test case for this, which I'll merge when I make a new timelib release (shortly).
