Operating system: Linux 2.4.16C12
PHP version: 4.3.6
PHP Bug Type: Date/time related
Bug description: Some wrong dates when using gtdate()/mktime()
Description:
------------
When you want to display each 10/31/Year plus 1 day, you've got sometimes
10/31/Year instead of 11/01/Year.
Noticed on PHP 4.3.3 (ISP linux server) and PHP 4.3.6 (WinXP personal
system)
Getting the date with date("m/d/Y", mktime(0,0,0,10,31,$i)+(24*3600));
gives the same result exept for 11/1/1993
Reproduce code:
---------------
<?php
for ($i = 1990 ;$i < 2011 ; $i++) {
$date = getdate(mktime(0,0,0,10,31,$i)+(24*3600));
echo $date['mon']."/".$date['mday']."/".$date['year']."\n";
}
?>
Expected result:
----------------
11/1/1990
11/1/1991
11/1/1992
11/1/1993
11/1/1994
11/1/1995
11/1/1996
11/1/1997
11/1/1998
11/1/1999
11/1/2000
...
Actual result:
--------------
11/1/1990
11/1/1991
11/1/1992
10/31/1993
11/1/1994
11/1/1995
11/1/1996
11/1/1997
11/1/1998
10/31/1999
11/1/2000
11/1/2001
11/1/2002
11/1/2003
10/31/2004
11/1/2005
11/1/2006
11/1/2007
