No it's not unambigious:
$ php -r 'date_default_timezone_set("Europe/London"); echo
date_create()->format(DateTime::ISO8601), "\n";'
2012-09-02T18:17:36+0100
$ php -r 'date_default_timezone_set("Africa/Niamey"); echo
date_create()->format(DateTime::ISO8601), "\n";'
2012-09-02T18:19:05+0100
vs:
$ php -r 'date_default_timezone_set("Africa/Niamey"); echo
date_create("2012-12-31")->format(DateTime::ISO8601), "\n";'
2012-12-31T00:00:00+0100
^^^^^
$ php -r 'date_default_timezone_set("Europe/London"); echo
date_create("2012-12-31")->format(DateTime::ISO8601), "\n";'
2012-12-31T00:00:00+0000
^^^^^
