Description:
------------
(Note: I was only able to test on 5.2.16, 5.3.0, and 5.3.4.  Since there is no 
evidence of it being fixed in the changelog of 5.3.8, I assume it's still there.)

The ninth of May, 2010, was a Sunday.  However, if you assert to strtotime() that 
it was a Monday, it will return the Unix timestamp for Monday, May 10th.  Likewise 
if you assert the ninth was a Tuesday, it will return the timestamp for the 11th; 
a Wednesday the 12th, and so on right up to returning a Unix timestamp for 
Saturday, 15 May 2010 if you provide it with "Saturday, 9 May 2010".

Presumably, the correct behavior is one of (1) to throw an error given a self-
contradictory date, (2) to return nothing at all, or (3) to ignore the day-of-the-
week element and return the Unix timestamp for the date specified (e.g. 9 May 
2010).  Returning the timestamp for another date altogether is wrong.

Test script:
---------------
$datestring="9 May 2010 04:24:36 GMT";
print "\"\": ".strtotime($datestring)." ".date($dateformat, strtotime($datestri\
ng)) ."\n";

$datestring="Sun, 9 May 2010 04:24:36 GMT";
print "Sun: ".strtotime($datestring)." ".date($dateformat, strtotime($datestrin\
g)) ."\n";

$datestring="Mon, 9 May 2010 04:24:36 GMT";
print "Mon: ".strtotime($datestring)." ".date($dateformat, strtotime($datestrin\
g)) ."\n";

$datestring="Tue, 9 May 2010 04:24:36 GMT";
print "Tue: ".strtotime($datestring)." ".date($dateformat, strtotime($datestrin\
g)) ."\n";
