    Description

    Description: When passing ISO_8601-compliant dates, complete with timezone, one expects Zend_Date to properly accept and parse that date. However, it does not.

    Note the actual result below, Zend_Date ignores the timezone on the date and instead assumes the local timezone (which for me was America/New_York) while DateTime does not.

    Code:

    <?php $time = '2010-07-29 17:11:52.241004+00'; $dt = new DateTime($time); $dt2 = new Zend_Date($time, Zend_Date::ISO_8601); echo 'Time: ' . $time . '
    '; echo 'DateTime: ' . $dt->format('c') . '
    '; echo 'Zend_Date: ' . $dt2->get(Zend_Date::ISO_8601); ?>

    Expected Result: Time: 2010-07-29 17:11:52.241004+00 DateTime: 2010-07-29T17:11:52+00:00 Zend_Date: 2010-07-29T17:11:52+00:00

    Actual Result:

    Time: 2010-07-29 17:11:52.241004+00 DateTime: 2010-07-29T17:11:52+00:00 Zend_Date: 2010-07-29T17:11:52-04:00

    Actually wether the millisecond part nor the truncated timezone are proper ISO_8601 inputs.

    According to the Wikipedia article on ISO 8601, the truncated UTC offset is valid. (See http://en.wikipedia.org/wiki/ISO_8601/… for more)

    The fractional time is not ISO 8601; however, the removal of this does not affect the bug.
