Java Convert Timestamp to OffsetDateTime

Tags: Java Timestamp Java OffsetDateTime Java 8

In this Java core tutorial we learn how to convert a java.sql.Timestamp object to a java.time.OffsetDateTime object in Java programming language.

How to convert Timestamp to OffsetDateTime in Java

In Java, with a given Timestamp object we can follow these step to convert it to a OffsetDateTime object.

  • Step 1: use the Timestamp.toLocalDateTime() method to convert the Timestamp object to a LocalDateTime object.
  • Step 1: use the LocalDateTime.atOffset(ZoneOffset offset) method to convert the LocalDateTime object of step 1 to a OffsetDateTime object.

ConvertTimestampToOffsetDateTimeExample1.java 

import java.sql.Timestamp;
import java.time.Instant;
import java.time.LocalDateTime;
import java.time.OffsetDateTime;
import java.time.ZoneId;
import java.time.ZoneOffset;

public class ConvertTimestampToOffsetDateTimeExample1 {
    public static void main(String... args) {
        Timestamp timestamp = new Timestamp(System.currentTimeMillis());

        // Convert Timestamp object to OffsetDateTime object
        LocalDateTime localDateTime = timestamp.toLocalDateTime();
        ZoneOffset systemZoneOffset = ZoneId.systemDefault().getRules().getOffset(Instant.now());
        OffsetDateTime offsetDateTime = localDateTime.atOffset(systemZoneOffset);

        System.out.println("Timestamp: " + timestamp);
        System.out.println("OffsetDateTime: " + offsetDateTime);
    }
}
The output as below. 
Timestamp: 2022-05-24 18:43:44.902
OffsetDateTime: 2022-05-24T18:43:44.902+07:00
