note 51422 added to function.date

It seems that there is some thing wrong with this date( ) function. The following is my code. I want to get the "month" of last month and the "month" before last month in my application. However, for the "month" before last month, the result is correct, for the last month, the result is curent month( obviously, it is wrong ). I did not find this problem before only today (Mar 30, 2005). $currentmonth = date("Y-m-d",mktime(0, 0, 0, date("m"), date("d"), date("Y"))); $lastmonth = date("Y-m-d", mktime(0, 0, 0, date("m")-1, date("d"), date("Y"))); $pre2month = date("Y-m-d", mktime(0, 0, 0, date("m")-2, date("d"), date("Y"))); echo ' this month: '.$currentmonth.' || last month'.$lastmonth.' lastlast month: '.$pre2month; this month: 2005-03-30 || last month2005-03-02 lastlast month: 2005-01-30 However, if I change date("d") to 1, the results are correct. I think this is perhaps a small bug in the computation of the time in the mktime( ). ---- Manual Page -- http://www.php.net/manual/en/function.date.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+51422 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+51422&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+51422&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+51422&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+51422&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+51422&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+51422&report=yes Search -- http://master.php.net/manage/user-notes.php
