Java Convert ZonedDateTime to Another Time Zone

Tags: Java ZonedDateTime Java 8 Java ZoneId

In this Java core tutorial we learn how to convert a java.time.ZonedDateTime object from a specified time zone to another time zone in Java programming language.

How to convert ZonedDateTime to Another Time Zone in Java

In Java, with a given ZonedDateTime object in specified time zone we can use the ZonedDateTime.withZoneSameInstant(ZoneId zone) method to get a new ZonedDateTime object in another time zone.

In the following example Java code we show how to use the ZonedDateTime.withZoneSameInstant(ZoneId zone) method convert ZonedDateTime object in Australia/Sydney time zone to Europe/Paris time zone.

ConvertZonedDateTimeToAnotherTimeZoneExample1.java 

import java.time.ZoneId;
import java.time.ZonedDateTime;

public class ConvertZonedDateTimeToAnotherTimeZoneExample1 {
    public static void main(String... args) {
        // Date and time in Australia/Sydney time zone
        ZonedDateTime sydneyZonedDateTime = ZonedDateTime.parse("2022-05-22T12:30:40+10:00[Australia/Sydney]");

        // Convert date and time to Europe/Paris time zone
        ZoneId zoneId = ZoneId.of("Europe/Paris");
        ZonedDateTime parisTimeZonedDateTime = sydneyZonedDateTime.withZoneSameInstant(zoneId);

        System.out.println(sydneyZonedDateTime);
        System.out.println(parisTimeZonedDateTime);
    }
}
The output as below. 
2022-05-22T12:30:40+10:00[Australia/Sydney]
2022-05-22T04:30:40+02:00[Europe/Paris]
