What are you talking about?  I've given you all the information you need to reproduce the bug
and the reason why it's a bug.  Why are you closing this case?  Note that I just retested with
the latest version of php and it is still not fixed yet.

No feedback was provided. The bug is being suspended because
we assume that you are no longer experiencing the problem.
If this is not the case and you are able to provide the
information that was requested earlier, please do so and
change the status of the bug back to "Re-Opened". Thank you.

Well if you didn't delete my original message, you wouldn't be changing the status to
feedback eh?  Funny enough, my original message was preserved when your system sent me an email
saying you don't have enough information.  As originally stated, ISO dates should support years
in this range and such years are used by astronomers.

Description:
------------
I am unable to create dates with years <= -10000 and >= 10000.  ISO 8601:2004E allows for this
under Expanded representations:

http://isotc.iso.org/livelink/livelink/4021199/ISO_8601_2004_E.zip?func=doc.Fetch&nodeid=4021199

ISO 8601:2004(E)
14 © ISO 2004 – All rights reserved
4.1.2.4 Expanded representations
If, by agreement, expanded representations are used, the formats shall be as specified below. The
interchange parties shall agree the additional number of digits in the time element year. In the
examples below
it has been agreed to expand the time element year with two digits.
a) A specific day
Basic format: ±YYYYYMMDD Example: +0019850412
Extended format: ±YYYYY-MM-DD Example: +001985-04-12
b) A specific month
Basic format: ±YYYYY-MM Example: +001985-04
Extended format: not applicable
c) A specific year
Basic format: ±YYYYY Example: +001985
Extended format: not applicable
d) A specific century
Basic format: ±YYY Example: +0019
Extended format: not applicable

Reproduce code:
---------------
Negative year:

<?php
$date = new DateTime('-10000-01-01 00:00:00');
echo $date->format('Y-m-d H:i:s');
?>

Positive year:

<?php
$date = new DateTime('10000-01-01 00:00:00');
echo $date->format('Y-m-d H:i:s');
?>

Expected result:
----------------
Negative year outputs:

-10000-01-01 00:00:00

Positive year outputs:

10000-01-01 00:00:00

Actual result:
--------------
Negative year outputs:

2000-01-01 00:00:00

Positive year outputs:

Fatal error: Uncaught exception 'Exception' with message 'DateTime::__construct():
Failed to parse time string (10000-01-01 00:00:00) at position 12 (0): Double time
specification' in /test.php:5
Stack trace:
#0 /test.php(5): DateTime->__construct('10000-01-01 00:...')
#1 {main}
  thrown in /test.php on line 5
