Java OffsetDateTime

The Java Instant class is an immutable and thread-safe class that represents an immutable date-time with an offset. The OffsetDateTime class can be used to store all date and time fields, For example, the value “22nd April 2019 at 10:20.30.123456789 +02:00” can be stored in an OffsetDateTime.

How to use

The OffsetDateTime class can be used when modeling date-time concepts in more details, or when communicating to a database or in a network protocol. Try the following examples to better understand –

Now example

The following example program shows how you can create an instance of OffsetDateTime and get the current date and time.

OffsetDateTimeExample1.javaCopy
import java.time.OffsetDateTime;

public class OffsetDateTimeExample1 {

    public static void main(String[] args) {

        // Create instance of OffsetDateTime
        OffsetDateTime offsetDateTime = OffsetDateTime.now();

        // Print local time
        System.out.println(offsetDateTime.toLocalTime());
    }
}
Try It

Add/Subtract example

The following example program shows how you can plus/minus days in OffsetDateTime.

OffsetDateTimeExample2.javaCopy
import java.time.OffsetDateTime;

public class OffsetDateTimeExample2 {

    public static void main(String[] args) {

        // Create instance of OffsetDateTime
        OffsetDateTime offsetDateTime = OffsetDateTime.now();
        System.out.println("Current: " + offsetDateTime.toLocalDate());

        // Add 5 days
        offsetDateTime = OffsetDateTime.now().plusDays(5);
        System.out.println("Plus 5 day: " + offsetDateTime.toLocalDate());

        // Subtract 5 days
        offsetDateTime = OffsetDateTime.now().minusDays(5);
        System.out.println("Minus 5 day: " + offsetDateTime.toLocalDate());
    }
}
Try It

Format example

The following example program shows how you can format date and time.

OffsetDateTimeExample3.javaCopy
import java.time.OffsetDateTime;
import java.time.format.DateTimeFormatter;

public class OffsetDateTimeExample3 {

    public static void main(String[] args) {

        // Create instance of OffsetDateTime
        OffsetDateTime offsetDateTime = OffsetDateTime.now();

        // Format date and time
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd-MMM-yyyy");
        String format = offsetDateTime.format(formatter);
        System.out.println(format);
    }
}
