Description:
------------
Adding a negative number of seconds to a date via addSeconds does not modify the date.

Test script:
---------------
<?php
require_once 'Date.php';
$date = new Date('2006-11-21');

print "Date is now: " . $date->format("%Y-%m-%d %H:%M") . "\n";
$date->addSeconds(-1 * 86400 * 7); # subtract 1 week
print "After subtracting a week's worth of seconds, date is: " . $date->format("%Y-%m-%d %H:%M") . "\n";

Expected result:
----------------
Date should be decremented by the specified number of seconds

Actual result:
--------------
Date is unchanged.
