    Description

      Noticed while fixing QtPIM unit tests to work with Qt6.

      import QtQml 2.0

QtObject {
    id: root
    Component.onCompleted: {
        var testdate = new Date("1991-08-25 20:57:08 GMT+0000")
        console.log("Constructed JS date: " + testdate)
        console.log("As UTC String: " + testdate.toUTCString())
    }
}

      When run with Qt5 qmlscene we get:

      $ ../build/qt5/qtbase/bin/qmlscene testdate.qml
qml: Constructed JS date: Mon Aug 26 06:57:08 1991 GMT+1000
qml: As UTC String: Sun Aug 25 20:57:08 1991 GMT

      But when run with Qt6 qmlscene we get:

      $ ../build/qt6/qtbase/bin/qmlscene testdate.qml
qml: Constructed JS date: Invalid Date
qml: As UTC String: Invalid Date

      Ubuntu Linux 18.04 / gcc 7.5
