Description:
------------
I thought these two commands are equal:
DateTime::createFromFormat('U', 1343730289, new DateTimeZone("Europe/Prague"))
DateTime::createFromFormat('U', 1343730289)->setTimeZone(new DateTimeZone("Europe/Prague"))

However they aren't. If that behaviour is correct (I'm unsure) can you explain why are they different?

Test script:
---------------
var_export(
DateTime::createFromFormat('U', 1343730289)->setTimeZone(new DateTimeZone("Europe/Prague"))->getTimeZone()->getName() === DateTime::createFromFormat('U', 1343730289, new DateTimeZone("Europe/Prague"))->getTimeZone()->getName()
);

Expected result:
----------------
true

Actual result:
--------------
false

For the first "command" please see the note on the DateTime::createFromFormat() 
manual page [1] which states:

  The timezone parameter and the current timezone are ignored
  when the time parameter either contains a UNIX timestamp
  (e.g. 946684800) or specifies a timezone 
  (e.g. 2010-01-28T15:00:00+02:00).
