Java版世界時鐘樣本

這是一個Java版的世界時鐘樣本，移植自Gerrit建立的同名Swing應用（http://www.jug-muenster.de/swing-worldclock-427
），需要運行在JRE1.5或以上環境當中。

 

移植此樣本主要是因為前一陣移植過Gerrit的swing原子鐘樣本，所謂好事成雙，這個世界時鐘的樣本自然不能放過（話說Gerrit為什麼那麼喜歡做時鐘？……），畢竟Java案頭應用執行個體本就不多，但凡有參考價值的還是要多做匯總才好。

 

另外，此樣本中關於多時區的分辨與顯示部分，在非案頭應用中也具備一定的參考價值。

 

PS:由於此樣本以LGame-Simple-0.2.5開發，所以也可以看作是世界時鐘的AWT實現。

運行代碼如下所示（構建過程省略了Swing原版的一些步驟）：
