Heart-felt thanks to the heroic Ole Zorn who volunteered to translate the clock into German, not realising that he was about to experience a grueling 3-day schedule of testing and round-the-clock correspondence. Thanks Ole!
I now have a translation-ready clock. If you, or any of your kind friends are willing to do some translation then please get in touch. Now that Ole has been such a help, it’s pretty easy* to add other languages.
You can see the German version by going to System Preferences > International and making German your preferred language. Note that you must have German language support installed for this to work. Updated version now available
