Description:
------------
Executing the example from http://php.net/manual/en/mongodate.todatetime.php produces an incorrect DateTime value on Windows, works fine on Linux. 

Test script:
---------------
<?php
$d = new MongoDate(strtotime("2014-11-18 11:01:25"));
var_dump( $d->toDateTime() );

Expected result:
----------------
class DateTime#2 (3) {
  public $date =>
  string(26) "2014-11-18 11:01:25.000000"
  public $timezone_type =>
  int(1)
  public $timezone =>
  string(6) "+00:00"
}

Actual result:
--------------
object(DateTime)[8]
  public 'date' => string '1969-12-20 00:41:17.320000' (length=26)
  public 'timezone_type' => int 1
  public 'timezone' => string '+00:00' (length=6)
