Bug description:strtotime doesn't use current timezone on '4 thursdays'

Description:
------------
---
From manual page: http://www.php.net/function.strtotime
---
date_default_timezone_set('UTC');
$timestamp = mktime(0,0,0,11,1,2014);

strtotime('4 thursdays', $timestamp) does not return the same timestamp
as strtotime('first thursday + 3 weeks', $timestamp)

The first call returns a timestamp indicating a time of 6am (we are in
CST) and the second returns a timestamp indicating 12am.

Test script:
---------------
//The server timezone is America/Chicago
$timestamp = mktime(0,0,0,11,1,2014);
echo strtotime('4 thursdays', $timestamp) . "\n";
strtotime('first thursday + 3 weeks', $timestamp) . "\n";

Expected result:
----------------
Both should return the same timestamp indicating 12:00 am.
