java.util.TimeZone简介
java.util.TimeZone简介
java.util.TimeZone类的实例包含了一个与格林威治标准时间（GMT）相比较得出的以微秒为单位的时区偏移量，而且它还处理夏令时。要获得一个所有支持的进区的列表，你可以使用方法TimeZone.getAvailableIDs，它将返回一个包含了所有进区ID的字符串数组。要知道关于TimeZone类的更多细节，可以参看Sun公司的Web站点。
------------------------------------------------------------------------------------------------------------------------------------------
使用场景：
一般在实现了javax.servlet.Filter的Java类中的init(FilterConfigfilterConfig)方法中设置国际化时间差。
样例代码如下：
public void init(FilterConfigfilterConfig) throwsServletException{
TimeZoneuserTimeZone =TimeZone.getTimeZone(System.getProperty("user.timezone"));
TimeZonechinaTimeZone =TimeZone.getTimeZone("Asia/Shanghai");
if(!chinaTimeZone.hasSameRules(userTimeZone)){
TimeZone.setDefault(chinaTimeZone);
}
}
