Description:

On Linux PPC 32bit (Gentoo with following options: apache2 bcmath berkdb bzip2 cjk cli crypt ctype curl curlwrappers exif ftp gd gdbm iconv imap json ldap mhash mysql mysqli ncurses nls pcntl pcre posix readline reflection session simplexml snmp soap sockets spl ssl suhosin tidy tokenizer truetype unicode wddx xml xmlreader xmlrpc xmlwriter xpm xsl yaz zip zlib), the date('Y') don't generate the current year, but 0000.

A simple but not that nice work around is to make
'20'.date('y')

Using the date('Y') works on my x86_64, so I think the bug may be in just big endian machines (haven't tested this on my sparc yet).

Reproduce code:
---------------
<?php
echo date('Y');
?>

Expected result:
----------------
2009

Actual result:
--------------
0000
