In this tutorial, I am going to show how to set/change the time zone in spring boot application.

Spring Boot SetTimeZone :

JVM will take the default time zone as the server’s time zone. For example, if the server is running on IST, then the JVM takes the IST time as default.

In Spring boot we can quickly change/set this default timezone using java.util.TimeZone class like below.

package com.onlinetutorialspoint.SpringBoot_Custom_ErrorPage;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import javax.annotation.PostConstruct;
import java.util.Date;
import java.util.TimeZone;

@SpringBootApplication
public class Application {
  @PostConstruct
  public void init(){
    // Setting Spring Boot SetTimeZone
    TimeZone.setDefault(TimeZone.getTimeZone("IST"));
  }
  public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
  }
}

Run Application :

You can see the updated time zone while running the application above.

Happy Learning 🙂
