【原創】 JAVA UTC時間轉化為本地時間LocalDateTime

   public LocalDateTime convertUTCToLocalTime(String timeStamp) {
        Long timeLong = Long.parseLong(timeStamp) * 1000L;
        Date timeDate = new java.util.Date(timeLong);
        String date = new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(timeDate);
        DateTimeFormatter df = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
        LocalDateTime ldt = LocalDateTime.parse(date, df);
        return ldt;
    }
