Description:
------------
Howdy,
This is a php implementation on a cpanel box:
PHP 5.2.9 (cli) (built: Jun 5 2009 04:19:37)
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies

Today is 2010 - 10 - % and basically I have the following:
$thisMonth = date("Y-m-1");
this will return as expected: 2010-10-1
Then I have this:
$lastmonth = strftime("%Y-%m-1", strtotime("-1 months"));
Which does not return as expected, it returns: 2010-10-1 the same as
above.
Expected result would be: 2010-09-1
However I have tried alternative approaches such as naming.
$lastmonth = strftime("%Y-%m-1", strtotime("-1 month"));
Same thing.
Possible bug?
Test script:
---------------
<?php
echo date("Y-m-1"); //Returns 2010-10-1
echo "<br />";
echo strftime("%Y-%m-1", strtotime("-2 month")); // Returns 2010-08-1
echo "<br />";
echo strftime("%Y-%m-1", strtotime("-1 month")); // Unexpected: 2010-10-1
echo "<br />";
echo strftime("%Y-%m-1", strtotime("-1 months")); // Unexpected: 2010-10-1
?>
Expected result:
----------------
I expect that it would return a back roll of on month from the current
At the moment of posting this it is october, so it should roll to
september, delivering results:
2010-09-1
Actual result:
--------------
Well at the moment it is just returning the current month:
2010-10-1
