public static void main(String[] args) {
    // datetime string without a time zone or offset
    String utcTimestamp = "2020-05-25 08:03:24";
    // parse the datetime as it is to an object that only knows date and time (no zone)
    LocalDateTime datetimeWithoutZone = LocalDateTime.parse(utcTimestamp,
                                    DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
    // convert it to a zone-aware datetime object by adding a zone
    ZonedDateTime utcZdt = datetimeWithoutZone.atZone(ZoneId.of("UTC"));
    // print the datetime in utc once
    System.out.println(utcZdt);
    // then convert the zoned datetime to a different time zone
    ZonedDateTime asiaJakartaZdt = utcZdt.withZoneSameInstant(ZoneId.of("Asia/Jakarta"));
    // and print the result
    System.out.println(asiaJakartaZdt);
