QDateTime Isodate mit Zeitzone ?

Ich suche die Datumszeit von qt, um mir den String als Isodate zurückzugeben, aber mit der Zeitzone.
Ich habe manchmal im Internet nach meinem Problem gesucht, aber keine Lösung gefunden

Ich habe gerade das bekommen:

this->ui.dateEnd->dateTime().toString(Qt::ISODate);
 

gib mir das:

1900-10-31T23:00:00Z
 

Oder auch das:

this->ui.dateEnd->dateTime().toUfc().toString(Qt::ISODate);
 

gib mir das:

1900-10-31T23:00:00Z
 

und ich will das:

1900-10-31T23:00:00+01.00.00
 

Vielen Dank, wenn jemand eine Idee hat!

Antworten:

Habe den Fehler umgangen, den ich in den Kommentaren erwähnt habe:

QDateTime local = QDateTime::currentDateTime();
 QDateTime utc = local.toUTC();
 utc.setTimeSpec(Qt::LocalTime);
 int utcOffset = utc.secsTo(local);
 qDebug() << local.toString(Qt::ISODate);
 qDebug() << utc.toString(Qt::ISODate);
 qDebug() << utcOffset;
 local.setUtcOffset(utcOffset);
 qDebug() << local.toString(Qt::ISODate);
 

Dies gibt aus:

"2013-09-12T00:17:39"  
 "2013-09-11T21:17:39"  
 10800 
 "2013-09-12T00:17:39+03:00"

 qSwap(startDate, endDate);
// Make endDate before startDate. qDebug() << "Days from startDate to endDate: " << startDate.daysTo(endDate);
