Description:
------------
strtotime() fails when supplied with both a negative and positive argument. This worked in php 5.0.5 and php 4.x.x.

+- = -
++ = +
-- = +


Reproduce code:
---------------
$offset = -60;
$ts = strtotime('2000-01-01 12:00:00');
$result = date("Y-m-d H:i:s", strtotime("+$offset minutes", $ts));
echo $result;

Expected result:
----------------
2000-01-01 11:00:00

Actual result:
--------------
1970-01-01 01:00:00
