The current date/time can be obtained in QML using Javascript’s date:

var today = new Date() // contains current date and time

QML provides the Qt.formatDate() and Qt.formatDateTime() methods for formatting this value. You can also dynamically declare dates using the QML date basic type.

An example displaying the current date in YYMMDD format might look like:

Rectangle {
width: 200
height: 200
Text {
anchors.centerIn: parent
text: Qt.formatDateTime(new Date(), "yyMMdd")

Qt C++ API

The main Qt C++ methods for getting the current date and time are:

Headers required

#include <QDateTime>


SystemTime::SystemTime(QWidget *parent)
: QMainWindow(parent)
setWindowTitle("System Time");
ui.statusbar->showMessage("Showing system time");
//get current date
QDate date = QDate::currentDate();
QString dateString = date.toString();
ui.label->setText("Date: " + dateString);
//get current time
QTime time = QTime::currentTime();
QString timeString = time.toString();
ui.label_2->setText("Time: " + timeString);
//get current date and time
QDateTime dateTime = QDateTime::currentDateTime();
QString dateTimeString = dateTime.toString();
ui.label_3->setText("Date and Time: " + dateTimeString);


The code snippet is expected to show current date and time of device.


Code Example

  • The Code Example will show current date and time on screen and example is tested on Nokia 5800 XpressMusic.
