Description:
------------
the strtotime() function accepts a string with one or more spaces (' '), one or more dots  ('.') or one or more comma's (',') or a combination of these with no other valid date/time information as acceptable and returns a timestamp (now) instead of the expected FALSE.

Here is the output on a bunch of different PHP versions -> https://3v4l.org/kSH46

Test script:
---------------
<?php
	var_dump(strtotime(" "));
	var_dump(strtotime(","));
	var_dump(strtotime("."));
	var_dump(strtotime(". .. .. .. .... .. . .. ."));
	var_dump(strtotime(". .. .. .. ..,,,.. .. . .. ."));
	var_dump(strtotime("bogus"));

Expected result:
----------------
boolean false
boolean false
boolean false
boolean false
boolean false
boolean false

Actual result:
--------------
int 1443016200
int 1443016200
int 1443016200
int 1443016200
int 1443016200
boolean false
