Howdy,

This is a php implementation on a cpanel box:
PHP 5.2.9 (cli) (built: Jun  5 2009 04:19:37)

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
