This is expected behavior, but the documention on this function is
vague. I updated the documentation in the online manual which should be
online somewhere during this w.

timezone_offset_get() has the same problem.

Description:
------------
DateTime class already has a getOffset to returns DST offset. But
DateTimeZone has a parameter of DateTime, the result still returns only
the DateTimeZone DST offset itself ? Should not it returns the offset
between the DateTimeZone and the given parameter of DateTime ?

Reproduce code:
---------------
$dateTimeZoneTaipei = new DateTimeZone("Asia/Taipei");
$dateTimeZoneJapan = new DateTimeZone("Asia/Tokyo");

$dateTimeTaipei = new DateTime("now", $dateTimeZoneTaipei);
$dateTimeJapan = new DateTime("now", $dateTimeZoneJapan);

$timeOffset = $dateTimeZoneJapan->getOffset($dateTimeTaipei);
var_dump($timeOffset);


Expected result:
----------------
int(3600)

Actual result:
--------------
int(32400)
