      Sample program:

      #include <QDebug>
#include <QDateTime>

int main(int argc, char *argv[])
{
    QDateTime dt = QDateTime::fromString("1978-11-09T00:00:00+04:00", Qt::ISODate);
    qDebug() << dt << (dt.timeSpec() == Qt::OffsetFromUTC);
    qDebug() << dt.toString(Qt::ISODate);

    return 0;
}

      Output:
      QDateTime("Thu Nov 9 00:00:00 1978") true
      "1978-11-09T00:00:00"

      So the +04:00 offset is lost. This seems to be related to the missing "Z" for UTC times mentioned in http://bugreports.qt.nokia.com/browse/QTBUG-9698.

      This makes some synchronisation use-cases for qtcontacts-tracker really painful.
