QDateTime fromString ISO 8601 midnight issue

QDateTime handles the midnight notation "24:00" incorrectly. According to the standard, 24:00 one day is equivalent to 00:00 the next day.

From Wikipedia:
"Midnight is a special case and can be referred to as both "00:00" and "24:00". The notation "00:00" is used at the beginning of a calendar day and is the more frequently used. At the end of a day use "24:00". Note that "2007-04-05T24:00" is the same instant as "2007-04-06T00:00" (see Combined date and time representations below)."

Also see section 4.2.3 in http://dotat.at/tmp/ISO_8601-2004_E.pdf

This code:
QString testStr = "2012-02-23T24:00:00";
qDebug() << "QString:\t" << testStr;
QDateTime dateTime = QDateTime::fromString(testStr, Qt::ISODate);
qDebug() << "QDateTime:\t" << dateTime.toString(Qt::ISODate);

produces this output:
QString: "2012-02-23T24:00:00"
QDateTime: "2012-02-23T00:00:00"

According to the standard, the output should have been:
QString: "2012-02-23T24:00:00"
QDateTime: "2012-02-24T00:00:00"
