This applet shows the time in QR-Code.
I used the xzing library for encoding the time.
You can use the function QRCodezeichnen(String textstring,int posx,int posy,int breite) to to paint a qrcode with the information: textstring on the position: posx posy and the width: breite.
The Buttons on the screen should not be just rectangular, they should be shaped.
If you ever tried to make shaped buttons with any programming language, you know it is hard.
I found an unusual and very easy way to make buttons in any shape you like.
