WebIn Joda Time you'd use a DateTime value, which is an instant in time in a particular calendar system and time zone. In Java 8 you'd use java.time.ZonedDateTime, which is the Java 8 equivalent of Joda Time's DateTime. You can first create a ZonedDateTime with that time zone, and then call toInstant: LocalDateTime dateTime = LocalDateTime.of (2024, Month.JUNE, 15, 13, 39); Instant instant = dateTime.atZone (ZoneId.of ("Europe/Paris")).toInstant (); System.out.println (instant); // 2024-06-15T11:39:00Z.
