Get current Date and Time in Qt

QML

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:

• Template:Qapiname returns the current date and time, as reported by the system clock, in the local time zone.
• Template:Qapiname returns the current date, as reported by the system clock, in the local time zone.
• Template:Qapiname returns the current time, as reported by the system clock, in the local time zone.
