java ScheduledThreadPoolExecutor change timing of task

I am in the need of changing the executing time of a runnig task for a ScheduledThreadPoolExecutor.

i have something like

executor.schedule(new Runnable() {blablal},10,TimeUnit.SECONDS);

during the login phase, i would like to pick up all the tasks for this user and execute them once.

it's not possible to change the execution time of the ScheduledFuture right?

so my best option it's to do something like

synchronized(list) {
    Runnable a = new Runnable(){aaaa; list.remove(a)};
    executor.schedule(a,10,TimeUnit.SECONDS);
    list.add(a);
}

and at login

synchronize(list) {
    for (Runnable a : list) 
        a.run();
}

am i right?

there aren't any other better options, so i can avoid all this synchronization?

maybe a direct way to change the timeout of a ScheduledFuture

Keep a handle on the Future that is returned when you schedule something on the ScheduledExecutor. Instead of trying to change the execution time, you can cancel the future and re-schedule it.
