Bug description: DateTime::modify('last day') returns last day of the month
Description:
------------
call to modify('last day') has different effect in PHP 5.3 than in 5.2
It used to return a previous day, now it seems to return last day of the
month,
according to
http://www.gnu.org/software/automake/manual/tar/General-date-syntax.html#SEC115
"last" means -1 so 5.2 seems to get it right
Reproduce code:
---------------
date_default_timezone_set('Europe/London');
$dt = new DateTime('today');
var_dump($dt->format('c'));
$dt->modify('last day');
var_dump($dt->format('c'));
$dt = new DateTime('01-04-2009');
var_dump($dt->format('c'));
$dt->modify('last day');
var_dump($dt->format('c'));
Expected result:
----------------
PHP 5.2.11 (cli) (built: Sep 18 2009 10:59:00)
string(25) "2009-10-16T00:00:00+01:00"
string(25) "2009-10-15T00:00:00+01:00"
string(25) "2009-04-01T00:00:00+01:00"
string(25) "2009-03-31T00:00:00+01:00"
Actual result:
--------------
PHP 5.3.0 (cli) (built: Jul 21 2009 17:02:21)
string(25) "2009-10-16T00:00:00+01:00"
string(25) "2009-10-31T00:00:00+00:00"
string(25) "2009-04-01T00:00:00+01:00"
string(25) "2009-04-30T00:00:00+01:00"
