Description:
------------
using "date_create('@'.$timestamp)" ignores the default timezone setting, giving the timezone as second parameter does not work either.

tested with 5.2.3-1ubuntu6.3, 5.2.0-8+etch10
and tested with snapshot: 5.3-200802121930

Reproduce code:
---------------
$t= time();
$tz= date_default_timezone_get();
$d1= date_create(date("c", $t));
$d2= date_create("@$t"); // ignores default timezone
$d3= date_create("@$t", new DateTimeZone($tz)); // ignores timezone too

echo "default timezone: $tz\n";
echo $d1->format(DATE_RFC2822)."\n";
echo $d2->format(DATE_RFC2822)."\n";
echo $d3->format(DATE_RFC2822)."\n";


Expected result:
----------------
default timezone: Europe/Berlin
Tue, 12 Feb 2008 22:11:23 +0100
Tue, 12 Feb 2008 22:11:23 +0100
Tue, 12 Feb 2008 22:11:23 +0100


Actual result:
--------------
default timezone: Europe/Berlin
Tue, 12 Feb 2008 22:11:23 +0100
Tue, 12 Feb 2008 21:11:23 +0000
Tue, 12 Feb 2008 21:11:23 +0000

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Using @ with a time stamp, implicitly uses UTC as timezone. The default timezone or the timezone passed as 2nd argument will only be used if no TZ is associated with the string. As @ already makes UTC associated with it, they are ignored.
