How do I return when I finish / keep Timer / Schedulel?

So I'm developing a game project that uses RMI (client / server) and needed to manage the players' time-out. For example, if a player takes more than one minute to make his or her respective play, he loses.

The plays run through a loop, so I would need to check each interaction to see if the time is up. I was currently trying to do with the Timer / Schedulel classes, but I do not find a way to "save" the time and check when it's gone.

My question: How can I save / return the time it's currently running? Is there any mick or any class for this? I'm trying to achieve something like, for example:

Timer timer;
int tempoAtual;            // Variável para guardar tempo
boolean isAcabou = false;  // Variável para verificar termino
public Temporizacao(int seconds) {
    timer = new Timer();                        // Cria um novo Timer
    timer.schedule(new Teste(), seconds*1000);  // set tarefa...
}

class Teste extends TimerTask {
    public void run() {
        // tempoAtual  -> atualiza tempo atual (?)
        timer.cancel();
        isAcabou = true;  
    }
}

public static void main(String args[]) {
    new Temporizacao(5);        // set tarefa de 5seg

    if(tempoAtual != isAcabou){ // Variável matem o tempo salvo para fazer validações
    System.out.println("Acabou tempo.");
   }
}
