In the left pane, you've probably noticed an example of ColorClock in action. That example uses hms for its main Format and dnmy for its SwitchFormat. The AutoSwitch parameter is set to double so that the SwitchFormat text is shown once every 10 seconds and holds for 2 seconds.

The example above is similar, but its AutoSwitch parameter is set to twice so that it displays every five seconds for a second each time. Its Align parameter has been set to left. In addition, the 3D parameter is called into play, using the gray setting, and the 3DOffset parameter is set to 3 so that the effect will be more noticeable with this large font.
