        System.out.println(today.toString());
        String time=today.toString()+" 23:59:59";
        DateTimeFormatter ftf = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
        LocalDateTime parse = LocalDateTime.parse(time, ftf);
        parse= parse.plusHours(72);
        long todytime= LocalDateTime.from(parse).atZone(ZoneId.systemDefault()).toInstant().toEpochMilli();

        System.out.println(todytime/1000);
