Description:
------------
DateTime ignores Timezone:

php -r '$d=new DateTime("2012-02-09T15:30:14+0100"); echo $d->format(DATE_ISO8601)."\n"; $d=new DateTime("2012-02-09T14:30:14+0000"); echo $d->format(DATE_ISO8601)."\n";'

Output:
2012-02-09T15:30:14+0100
2012-02-09T14:30:14+0000


strtotime works as expected:

php -r 'echo date(DATE_ISO8601, strtotime("2012-02-09T15:30:14+0100"))."\n"; echo date(DATE_ISO8601, strtotime("2012-02-09T14:30:14+0000"))."\n";'

Output:
2012-02-09T15:30:14+0100
2012-02-09T15:30:14+0100


Test script:
---------------
php -r '$d=new DateTime("2012-02-09T15:30:14+0100"); echo $d->format(DATE_ISO8601)."\n"; $d=new DateTime("2012-02-09T14:30:14+0000"); echo $d->format(DATE_ISO8601)."\n";'


Expected result:
----------------
2012-02-09T15:30:14+0100
2012-02-09T15:30:14+0100


Actual result:
--------------
2012-02-09T15:30:14+0100
2012-02-09T14:30:14+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

DateTime objects actually keep their timezone information, whereas strtotime() removes it (as a timestamp doesn't contain tz info).
