Converts the date string dateString to a Date object using locale and format.

If format is not specified, Locale.LongFormat will be used.

If locale is not specified, the default locale will be used.

The following example shows the current date first being formatted as a date string using the default locale and format, then parsed back again in the same manner:

import QtQml 2.0

QtObject {
    property var locale: Qt.locale()
    property date currentDate: new Date()
    property string dateString

    Component.onCompleted: {
        dateString = currentDate.toLocaleDateString();
        print(Date.fromLocaleDateString(dateString));
    }
}

Converts the datetime string dateTimeString to a Date object using locale and format.

If format is not specified, Locale.LongFormat will be used.

If locale is not specified, the default locale will be used.

The following example shows a datetime being parsed from a datetime string in a certain format using the default locale:

import QtQml 2.0

QtObject {
    property var locale: Qt.locale()
    property string dateTimeString: "Tue 2013-09-17 10:56:06"

    Component.onCompleted: {
        print(Date.fromLocaleString(locale, dateTimeString, "ddd yyyy-MM-dd hh:mm:ss"));
    }
}

Converts the time string timeString to a Date object using locale and format.

If format is not specified, Locale.LongFormat will be used.

If locale is not specified, the default locale will be used.

The following example shows the current time first being formatted as a time string using the default locale and a short format, then parsed back again in the same manner:

import QtQml 2.2

QtObject {
    property var locale: Qt.locale()
    property date currentTime: new Date()
    property string timeString

    Component.onCompleted: {
        timeString = currentTime.toLocaleTimeString(locale, Locale.ShortFormat);
        print(Date.fromLocaleTimeString(locale, timeString, Locale.ShortFormat));
    }
}

Informs the JS engine that the system's timezone has been changed, which is necessary for the correct manipulation of datetime data.

JS stores Date objects in UTC time; all access to and from Date components in local time involves the application of the current offset from UTC. If the current offset changes due to the timezone being updated, the JS engine needs to be informed so that it can recalculate the offset.

This function should be called after the system's timezone has been updated.

For example, an application that changes the timezone would call timeZoneUpdated() after setting the new time zone:

property string selectedTimeZone

onSelectedTimeZoneChanged: {
    MyFunctions.setSystemTimeZone(selectedTimeZone)
    Date.timeZoneUpdated()
}

Converts the Date to a string containing the date suitable for the specified locale in the specified format.

If format is not specified, Locale.LongFormat will be used.

If locale is not specified, the default locale will be used.

The following example shows the current date formatted for the German locale:

import QtQuick 2.0

Text {
    text: "The date is: " + new Date().toLocaleDateString(Qt.locale("de_DE"))
}

Converts the Date to a string containing the date and time suitable for the specified locale in the specified format.

If format is not specified, Locale.LongFormat will be used.

If locale is not specified, the default locale will be used.

The following example shows the current date and time formatted for the German locale:

import QtQuick 2.0

Text {
    text: "The date is: " + new Date().toLocaleString(Qt.locale("de_DE"))
}

Converts the Date to a string containing the time suitable for the specified locale in the specified format.

If format is not specified, Locale.LongFormat will be used.

If locale is not specified, the default locale will be used.

The following example shows the current time formatted for the German locale:

import QtQuick 2.0

Text {
    text: "The date is: " + new Date().toLocaleTimeString(Qt.locale("de_DE"))
}
