Provide time zone to Spring @Scheduled?

Your code should be like this:

@Scheduled(cron = "0 0 14 * * *", zone = "GMT-5")
    public void execute() {
     // do scheduled job
}

"Zone" is gonna be the desired country's timezone.

Here is a nice tutorial about scheduled tasks with Spring:

https://www.baeldung.com/cron-expressions

It turned out that I could not use the @Scheduled annotation, but I implemented a work-around. In the JavaDoc of the SchedulingConfigurer it is stated that:

[SchedulingConfigurer is] Typically used for setting a specific TaskScheduler bean to be used when executing scheduled tasks or for registering scheduled tasks in a programmatic fashion as opposed to the declarative approach of using the @Scheduled annotation.

Next, I changed the cron job to implement the Runnable interface and then updated my configuration file to implement the SchedulingConfigurer, see below:

@Configuration
@EnableScheduling
@ComponentScan("package.that.contains.the.runnable.job.bean")
public class JobConfiguration implements SchedulingConfigurer {

    private static final String cronExpression = "0 0 14 * * *";
    private static final String timeZone = "CET";

    @Autowired
    private Runnable cronJob;

    @Bean
    CronTrigger cronTrigger() {
        return new CronTrigger(cronExpression, TimeZone.getTimeZone(timeZone));
    }

    @Override
    public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
        taskRegistrar.addCronTask(new CronTask(job, cronTrigger()));
    }
}

Please read the JavaDoc of the @EnableScheduling for more information.

Update

As of Spring 4, Spring Jira issue SPR-10456 has been resolved. Consequently, the @Scheduled annotation has a new zone attribute for exactly this purpose, e.g.

@Scheduled(cron = "0 0 14 * * *", zone = "CET")
public void execute() {
    // do scheduled job
}

You can also use time zone with @Scheduled tag in spring-boot like this :

@Scheduled(cron = "0 0 14 * * *" , zone = "GMT+5:00")
public void execute() {
    // do the scheduled job
}

There is element zone in annotation @Scheduled, starting from version 4.0.

You can insert a timezone as a string that can be accepted by java.util.TimeZone.
