Qt to QML conversion: QDateTime -> date

So I'm sending a QDateTime to QML in order to display it and do some checkings (ideally I would like to be able to use all javascript date functions like getTime(),getMonth()...), and I realized if I send:

QDateTime(2019-10-30 11:15:00.000 CET Qt::TimeZone Europe/Amsterdam )

And then I read the date on QML, I get the time on the local timezone instead of the one set on the QDateTime...

Wed Oct 30 06:15:00 2019 GMT-0400 (NY timezone)

Is there any way I can keep the timezone in the QML side? Thanks!!

Solution

  • Following the @Pedro's advice (I don't know how to tag you properly...), I used moment.js as well as moment-timezone.js so I could reference any date to the timezone I want. To anyone interested, that's how I did it:

    import QtQuick 2.9
import "./moment.js" as Moment
import "./moment-timezone-with-data.js" as MomentTimezone

Item {
    anchors.fill: parent
    property date customDate: new Date(); // local timezone is "America/New_York"

    function getDateWithTimeZone(date, timeZone) {
        var momentDate = moment(new Date(date));
        var momentDateTz = momentDate.tz(timeZone);
        return momentDateTz;
    }

    Text {
        anchors.centerIn: parent
        text: customDate.toLocaleString() + "\n"
              + getDateWithTimeZone(customDate, "Europe/Paris").toString()
    }
}

    which gives the following output:
