In this Java core tutorial we learn how to convert a java.time.LocalDateTime object to a java.util.Date in UTC time zone offset.

How to convert LocalDateTime to UTC Date in Java

In Java, with a given LocalDateTime object we can follow these steps to convert it to an UTC Date object.

  • Step 1: use the LocalDateTime.toInstant(ZoneOffset offset) method to convert the LocalDateTime object to an Instant object at UTC time zone offset.
  • Step 2: use the Date.from(Instant instant) method to instantiate a new Date object from Instant object of step 1.

ConvertLocalDateTimeToUTCDateExample1.java 

import java.time.Instant;
import java.time.LocalDateTime;
import java.time.ZoneOffset;
import java.util.Date;

public class ConvertLocalDateTimeToUTCDateExample1 {
    public static void main(String... args) {
        LocalDateTime localDateTime = LocalDateTime.parse("2022-05-29T07:30:20");

        // Convert LocalDateTime object to UTC Date object
        Instant instant = localDateTime.toInstant(ZoneOffset.UTC);
        Date date = Date.from(instant);

        System.out.println("LocalDateTime: " + localDateTime);
        System.out.println("UTC Date: " + date);
    }
}
The output as below. 
LocalDateTime: 2022-05-29T07:30:20
UTC Date: Sun May 29 14:30:20 ICT 2022
