QDateTime:currentDateTime().toString(ISO:Date) does not display time zone

[btse]

Using Qt5.11.2:
QDateTime::currentDateTime().toString(Qt::ISODate) does not include the timezone.
The above for me produces 2019-02-01T10:49:13 without the expected offset from UTC at the end.

Is there a correct way to get this string?

http://doc.qt.io/qt-5/qdatetime.html#toString-1:
"If the format is Qt::ISODate, the string format corresponds to the ISO 8601 extended specification for representations of dates and times, taking the form yyyy-MM-ddTHH:mm:ss[Z|[+|-]HH:mm], depending on the timeSpec() of the QDateTime. If the timeSpec() is Qt::UTC, Z will be appended to the string; if the timeSpec() is Qt::OffsetFromUTC, the offset in hours and minutes from UTC will be appended to the string."
http://doc.qt.io/qt-5/qdatetime.html#currentDateTime:
"Returns the current datetime, as reported by the system clock, in the local time zone."

So I don't see why the timezone should be appended.
