Description:
------------
The documentation claims that strtotime assumes US-English format; however, when the fields are separated with dashes, it reverts to UK-English format. 

Reproduce code:
---------------
$ICDate = "05-01-2012"; //actual code read from a file
$ICtimestamp = strtotime($ICDate);
$date = date ("F jS, Y", $ICtimestamp);
print $date; //actual code parsed through a template to display on a webpage

Expected result:
----------------
"May 1st, 2012"

Actual result:
--------------
"January 5th, 2012"
