QDateTime Isodate with timezone ?

Question

I'm looking for the datetime from qt to return me the string as an isodate but with the timezone. I looked on the web for sometimes for my problem but found no solution

I just got this:

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

giving me this:

1900-10-31T23:00:00Z

Or also this:

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

giving me this:

1900-10-31T23:00:00Z

and i want this:

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

Thank you if someone have an idea!

Answer 1

Got around the bug that I mentioned in the comments:

QDateTime local = QDateTime::currentDateTime();
QDateTime utc = local.toUTC();
utc.setTimeSpec(Qt::LocalTime);

qint64 const utcOffset = utc.secsTo(local);

qDebug() << local.toString(Qt::ISODate);
qDebug() << utc.toString(Qt::ISODate);
qDebug() << utcOffset;

local.setUtcOffset(utcOffset);
qDebug() << local.toString(Qt::ISODate);

This outputs:

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