时钟代码提供了各种接口，可以在HTML文件中设置，变化出多姿多彩的时钟模型，

参数说明见代码内info数组



时钟的绘制采用双缓冲图形处理机制，即先在缓冲区内绘制图形，再把图形显示到网页上可以有效的防止闪烁。



另外时钟的不断绘制是通过一个线程不断读取系统时间，如果时间有变化即绘制。采用一个线程绘制，一个线程处理网页比较符合APPLET设置规范。-Clock code provides a variety of interfaces, can be set in the HTML file, change a colorful clock model, the parameters described in the info array of the code to draw the clock graphics double buffering mechanism, which is to draw pictures in the buffer zone, graphical display to the page then you can effectively prevent flicker. In addition the clock continues to draw a thread through the system continuously reads the time, there is a change that is if the time to draw. Drawn by a thread, a thread page APPLET set more in line with specifications.
