Java ZoneOffset

The Java ZoneOffset class is an immutable and thread-safe class that represents the fixed zone offset from UTC time zone. Different parts of the world have several time-zone offsets.

How to use

The zone-offset is usually a fixed number of hours and minutes. The ZoneOffset class can be used to represent a time-zone offset from Greenwich/UTC, such as +02:00. Try the following examples to better understand –

ZoneOffset from UTC example

The following example program shows how you can create an instance of ZoneOffset with UTC and print the zone id.

ZoneOffsetExample1.javaCopy
import java.time.ZoneOffset;
import java.time.ZonedDateTime;
import java.time.temporal.Temporal;

public class ZoneOffsetExample1 {

    public static void main(String[] args) {

        // Zone offset from UTC
        ZoneOffset zone = ZoneOffset.UTC;

        // Print id
        System.out.println(zone.getId());

        Temporal temp = zone.adjustInto(ZonedDateTime.now());

        System.out.println(temp);
    }
}

ZoneOffset ofHoursMinutesSeconds() example

The following example program shows how you can ofHoursMinutesSeconds() function to create instance of a ZoneOffset.

ZoneOffsetExample2.javaCopy
import java.time.ZoneOffset;

public class ZoneOffsetExample2 {

    public static void main(String[] args) {

        // Zone offset from hours minutes and seconds.
        ZoneOffset zone = ZoneOffset.ofHoursMinutesSeconds(02, 05, 30);

        // Print the id
        System.out.println(zone.getId());

    }
}

ZoneOffset isSupported() example

The following example program shows how you can use isSupported() function with ZoneOffset.

ZoneOffsetExample3.javaCopy
import java.time.ZoneOffset;
import java.time.temporal.ChronoField;

public class ZoneOffsetExample3 {

    public static void main(String[] args) {

        // Zone offset from UTC
        ZoneOffset zone = ZoneOffset.UTC;

        // Offset seconds supported?
        boolean supported = zone.isSupported(ChronoField.OFFSET_SECONDS);
        System.out.println(supported);

        // Hour of date supported?
        supported = zone.isSupported(ChronoField.HOUR_OF_DAY);
        System.out.println(supported);

    }
}
