Description:
------------
strtotime parses some forms of characters (probably as long as there is a separation with dots) to timestamps.
If there's no real date, it fails to return false.

date_default_timezone_set has been properly set

Reproduce code:
---------------
date_default_timezone_set('Europe/Amsterdam');
$time = strtotime("T.B.A.");
var_dump($time);
$time = strtotime("T.BA.");
var_dump($time);
$time = strtotime("TB.A.");
var_dump($time);
$time = strtotime("TBA");
var_dump($time);

Expected result:
----------------
bool(false)
bool(false)
bool(false)
bool(false)

Actual result:
--------------
int(somenumberthatchanges)
int(somenumberthatchanges)
bool(false)
bool(false)
