+    \qmlclass Timer QmlTimer
+    \brief The Timer item triggers a handler at a specified interval.
+
+    A timer can be used to trigger an action either once, or repeatedly
+    at a given interval.
+
+    Here is a timer that shows the current date and time, and updates
+    the text every 500 milliseconds:
+
+    \qml
+    Timer {
+        interval: 500; running: true; repeat: true
+        onTriggered: time.text = Date().toString()
+    }
+    Text {
+        id: time
+    }
+    \endqml
+
+    QmlTimer is synchronized with the animation timer.  Since the animation
+    timer is usually set to 60fps, the resolution of QmlTimer will be
+    at best 16ms.
+
+    If the Timer is running and one of its properties is changed, the
+    elapsed time will be reset.  For example, if a Timer with interval of
+    1000ms has its \e repeat property changed 500ms after starting, the
+    elapsed time will be reset to 0, and the Timer will be triggered
+    1000ms later.
