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:...')

  thrown in /test.php on line 5
