TimeZone

    @Test
    public void test() {
        // 获得默认时区
        TimeZone defaultTZ = TimeZone.getDefault();
        // 获得上海时区
        TimeZone shanghaiTZ = TimeZone.getTimeZone("Asia/Shanghai");
        // 获得上海时区
        TimeZone chinaTZ = TimeZone.getTimeZone("GMT+08:00");
        // 获得UTC时区
        TimeZone utc = TimeZone.getTimeZone("UTC");
        // 获得GMT时区
        TimeZone gmt = TimeZone.getTimeZone("GMT");

        System.out.println(defaultTZ);
        System.out.println(shanghaiTZ);
        System.out.println(chinaTZ);
        System.out.println(utc);
        System.out.println(gmt);
    }

结果:
