Set custom system date to Scheduler

Question

I need to execute scheduled tasks with customizable system dates, for example, I should be able to set the scheduler date to 2019-01-15, in this scenario, the scheduler must execute all tasks scheduled on that date, understanding that the current date is 2019-02-12. At the moment, I've seen solutions only for time zone, using Spring or Quartz. Thanks!.

How do you expect to execute the tasks on 2019-01-15 if the date is in the past ? — Alan Kavanagh, Feb 12 '19 at 14:52
@AK47 that's the problem, I need to set the scheduler system date to X, and at the same time I've could have scheduled tasks to be executed at `code`"0 0 17 ? * MON,WED,FRI" — Christian Carreño Morales, Feb 12 '19 at 15:04

Use the TaskScheduler module:

private TaskScheduler scheduler;

Runnable exampleRunnable = new Runnable(){
    @Override
    public void run() {
        System.out.println("Executing task");
    }
};

@Async
public void executeTaskT() {
    ScheduledExecutorService localExecutor = Executors.newSingleThreadScheduledExecutor();
    scheduler = new ConcurrentTaskScheduler(localExecutor);

    DateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy");
    Date scheduledDate = dateFormat.parse("12-02-2019", dateFormat);

    scheduler.schedule(exampleRunnable, scheduledDate);
}

executeTaskT(); //call it somewhere after the spring application has been configured
