Bug description: possible leap year strtotime hiccup
Description:
------------
The clients server is hosted by a third party running debian SMP Apache
and PHP 4.3.4. The use of strtotime("next monday") skips monday the 1st
and returns monday the 8th when run on Feb. 28th (tomorrow is a leap
day.)
The servers particulars:
[dali]$ uname -a
Linux dali 2.4.24-grsec+w+fhs5+gr1913+nfs+++p3+c3+bu+gr0b-v6.182 #1 SMP
Mon Jan 5 12:43:44 PST 2004 i686 unknown
[dali]$ date
Sat Feb 28 14:33:39 PST 2004
Reproduce code:
---------------
[dali]$ cat t1.php
<?
$start = strtotime('next monday');
echo ('Start timestamp: '.$start.'<br>'."\n");
$first = strtotime('first Monday',$start);
echo ('"First" Monday: '.date('l, M d Y',$first).'<br>'."\n");
$oneth = strtotime('1 Monday',$start);
echo ('"1" Monday: '.date('l, M d Y',$oneth).'<br>'."\n");
$next = strtotime('next Monday',$start);
echo ('"Next" Monday: '.date('l, M d Y',$next).'<br>'."\n");
$twoth = strtotime('2 Monday',$start);
echo ('"2" Monday: '.date('l, M d Y',$twoth).'<br>'."\n");
$third = strtotime('third Monday',$start);
echo ('"Third" Monday: '.date('l, M d Y',$third).'<br>'."\n");
$threeth = strtotime('3 Monday',$start);
echo ('"3" Monday: '.date('l, M d Y',$threeth).'<br>'."\n");
?>
Expected result:
----------------
[dali]$ php t1.php
Content-type: text/html
X-Powered-By: PHP/4.3.4
Start timestamp: 1078732800<br>
"Next" Monday: Monday, Mar 01 2004<br>
"First" Monday: Monday, Mar 01 2004<br>
"1" Monday: Monday, Mar 01 2004<br>
"Next" Monday: Monday, Mar 08 2004<br>
"2" Monday: Monday, Mar 08 2004<br>
"Third" Monday: Monday, Mar 15 2004<br>
"3" Monday: Monday, Mar 15 2004<br>
[dali]$
Actual result:
--------------
[dali]$ php t1.php
Content-type: text/html
X-Powered-By: PHP/4.3.4
Start timestamp: 1078732800<br>
"Next" Monday: Monday, Mar 08 2004<br>
"First" Monday: Monday, Mar 08 2004<br>
"1" Monday: Monday, Mar 08 2004<br>
"Next" Monday: Monday, Mar 15 2004<br>
"2" Monday: Monday, Mar 15 2004<br>
"Third" Monday: Monday, Mar 22 2004<br>
"3" Monday: Monday, Mar 22 2004<br>
[dali]$
