Java World Clock example

This is a Java version of The World Clock example, transplanted from Gerrit created by the same name swing application (http://www.jug-muenster.de/swing-worldclock-427
To run in jre1.5 or above.

 

The main reason for porting this example is that the previous example of a swing atomic clock with Gerrit has been transplanted. The so-called "good" is a pair, and the example of a world clock cannot be used. (Why do Gerrit like clock so much ?......), After all, there are not many Java Desktop Application Instances, but any useful examples should be summarized.

 

In addition, the multi-time zone resolution and Display section in this example also has some reference value in non-desktop applications.

 

PS: Since this example is developed in LGame-Simple-0.2.5, it can also be seen as the AWT implementation of the world clock.
