No, this is a bug. This should work properly. Although it should *not* adjust for DST changeovers.

Description:
------------
When using a timezone abbreviation (e. g. CEST) instead of a geographical timezone name (e. g.
Europe/Berlin) in the DateTimeZone constructor, the resulting time offset is that of the
corresponding non-DST timezone, coming up an hour short.

Test script:
---------------
$dt = new DateTime(
'2017-05-16T10:11:32',
new DateTimeZone('CEST')
);
var_dump($dt);
var_dump($dt->format('c'));
Expected result:
----------------
object(DateTime)#1 (3) {
["date"]=>
string(26) "2017-05-16 10:11:32.000000"
["timezone_type"]=>
int(2)
["timezone"]=>
string(4) "CEST"
}
string(25) "2017-05-16T10:11:32+02:00"
Actual result:
--------------
object(DateTime)#1 (3) {
["date"]=>
string(26) "2017-05-16 10:11:32.000000"
["timezone_type"]=>
int(2)
["timezone"]=>
string(4) "CEST"
}
string(25) "2017-05-16T10:11:32+01:00"
