Java日期、时区的处理

Timestamp 时区

 

        Calendar cal = Calendar.getInstance();
        Date date = cal.getTime();

        System.out.println(date);

        Timestamp time = new Timestamp(date.getTime());

        System.out.println("time: "+time);
        
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSSSSz");
        sdf.setTimeZone(TimeZone.getTimeZone("GMT+8"));
//        sdf.setTimeZone(cal.getTimeZone());

        String sdate = sdf.format(date);

        System.out.println(sdate);

        System.out.println(cal.getTimeZone().getDisplayName());
        System.out.println(TimeZone.getTimeZone("GMT+8").getID());
