Description:
------------
After upgrading to 5.3.0 RC2, date('Y') always returns 0000. No php.ini setting (date.timezone) seems to have any influence.

date('y') works as expected and returns 09.

This Problem did not occur with 5.3.0RC1.

Reproduce code:
---------------
marvin:~/src/php-5.3.0RC2 thomas$ ./sapi/cli/php 
<?=date('Y') ?>
0000

Expected result:
----------------
marvin:~/src/php-5.3.0RC2 thomas$ ./sapi/cli/php 
<?=date('Y') ?>
2009

Actual result:
--------------
marvin:~/src/php-5.3.0RC2 thomas$ ./sapi/cli/php 
<?=date('Y') ?>
0000

Bleh, wrong link. Anyway, I can not reproduce this on Linux.
 [2009-05-14 08:48 UTC] info at programmiernutte dot net 
Me neither, I have 5.3.0RC2 flawlessly working on Linux, 
The issue occurs on my development system on Mac OS X 10.4 PPC only with 
5.3.0RC2. RC1 works correct. Strange, I know.
 [2009-05-14 09:05 UTC] derick@php.net 
Could you provide access? I don't have the possibility to test and debug on this specific platform myself.

DateTime is also affected:

$oDateTime = new DateTime();
    
print_r($oDateTime);

Result:
DateTime Object
(
    [date] => 0000-05-24 21:27:10
    [timezone_type] => 3
    [timezone] => Europe/Berlin
)
 [2009-05-25 05:37 UTC] derick@php.net 
I still can't reproduce this, and I still don't have access to this platform.

I cannot reproduce this on OS X 10.5.7 with PHP 5.3.0RC2.

$oDateTime = new DateTime();
print_r($oDateTime);

Result:
DateTime Object
(
    [date] => 2009-05-27 14:57:33
    [timezone_type] => 3
    [timezone] => America/Phoenix
)

echo date('y');
Result:
09

echo date('Y');
Result:
2009

PPC or Intel? I tested this on 10.4 and 10.5 on PPC with the same 
results.
 [2009-05-28 00:40 UTC] info at programmiernutte dot net 
I just verified the issue unter Linux PPC, Debian Lenny PPC to be 
specific.

So there is an endian issue somewhere.  How are you with gdb?  Could you set a breakpoint on the function and work your way through it and figure out where it goes south?
 [2009-05-28 03:56 UTC] scottmac@php.net 
We have a PPC test machine, Derick has access and I can set up other accounts if needed.
 [2009-05-28 08:42 UTC] derick@php.net 
Oh, I had forgotten about that PPC machine. I'll have a look.

Seems like it's an issue in slprintf:

1017			switch (format[i]) {
(gdb) 
1043					timelib_sll year = PHP_LLABS(t->y);
(gdb) print year
$1 = 1230768000
(gdb) next
1044					length = slprintf(buffer, 32, "%s%04ld", t->y < 0 ? "-" : "", year); break;
(gdb) print year
$2 = 2009
(gdb) next
1124			smart_str_appendl(&string, buffer, length);
(gdb) print buffer
$3 = "0000\000\000\004\202\000\000\000\000\000\000\000\000I\\\a\200\000\000\000\000\000\000\0006\000\000\000\000"
(gdb) next
1015		for (i = 0; i < format_len; i++) {
(gdb) print &string
$4 = (smart_str *) 0xffa1cde0
(gdb) print string
$5 = {c = 0x1071f060 "0000\020q�X\020c\003�", len = 4, a = 78}

This bug still exits in the same way with PHP 5.2.10.

Found after upgrade from 5.2.9 to 5.2.10 on a Mac OS X 10.4.11 Server 
PPC.

With 5.2.9 

     <?=date(Y); ?>

works as expected.
 [2009-06-21 11:17 UTC] rleeden at gmail dot com 
Also, seeing this after upgrading from 5.2.9 to 5.2.10.

On Solaris Sparc version 9.

     <?=date(Y); ?>

returns 0000 on 5.2.10
and returns 2009 as expected on 5.2.9

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
 
Thank you for the report, and for helping us make PHP better.

The year was a long long, but we were printing it like a long. Since sparc and ppc are big endian it was grabbing the wrong bits so to speak :)
