I'm getting this warning when trying to set a DateTime's timezone to
"America/Los_Angeles". I don't know what an ID is in this context, but surely
America/Los_Angeles has one... right? I'm using PHP 5.3.21 on OSX Mountain Lion.

Still the same in PHP 5.4.10.
This bug is more than 4 years old, could it be looked into?

I confirm the same on PHP 5.3.3, Debian 64bit.

I was able to reproduce this with PHP 5.2.9 from the commandline.
php -v
PHP 5.2.9 (cli) (built: May 1 2009 13:47:24)
$> php -r '$d = new DateTime("2009-01-01 00:00:00+0400");
$d->setTimezone($d->getTimezone());'

Description:
------------
If you set a time zone for a DateTime via DateTime::setTimeZone() and that time zone has no ID you
get an error message and the time zone will not be set.
This can lead to problems if you have two DateTime objects from a source you do not control and want
to format the second DateTime object in the same time zone as the first.
Reproduce code:
---------------
$d1 = new DateTime('2008-01-01 12:00:00 +02:00');
$d2 = new DateTime('2008-01-01 12:00:00 UTC');
echo $d1->format(DATE_ISO8601), PHP_EOL;
echo $d2->format(DATE_ISO8601), PHP_EOL;
$d2->setTimeZone($d1->getTimeZone());
echo $d1->format(DATE_ISO8601), PHP_EOL;
echo $d2->format(DATE_ISO8601), PHP_EOL;
Expected result:
----------------
2008-01-01T12:00:00+0200
2008-01-01T12:00:00+0000
2008-01-01T12:00:00+0200
2008-01-01T14:00:00+0200
Actual result:
--------------
2008-01-01T12:00:00+0200
2008-01-01T12:00:00+0000
