Reported By: mehmety at gmail dot com
Status: Bogus
Bug Type: Date/time related
Operating System: Linux
PHP Version: 5.2.0
New Comment:
We don't rely on it for the date stuff, but PHP *itself* only handles
normal signed integers. The following should work fine:
for ( $x = 0; $x < 99; $x++ )
{
$year = date_format(date_create( "+$x years" ), "Y");
echo "$x $year\n";
}

In that case, the PHP implimentation should not rely on a native
function.

This means you (i.e. the timestamp) have reached the limit of integer.
It's known problem and all *nix systems will face it in 2038. Not PHP
problem, though.

Description:
------------
In order to reproduce this bug, see the below source.
Using date and string to time ultimately causes the time to be reset
for the year. Seems like deviant behavior.
Reproduce code:
---------------
php -r 'for($x=0;$x<99;$x++){ $year=date("Y",strtotime("+$x
years"));echo "$x $year\n"; } exit();'
Expected result:
----------------
{0...98}{today's year + {0...98} }
Actual result:
--------------
