Boolean not changing values from one class to another

Question

I'm currently working on this Clash Royale style game in Java FX and I have a game timer in one class that I set in my test condition. However, when I check its value over on the GameView class it's always false. I've looked at many examples and the latest I tried making my properties static in my timer class but that didn't have any effect either. Hoping someone could steel me in the right direction. Thanks!

public class GameTimer  {
public int seconds = 180;
public static boolean endGame;


 public static boolean returnBool () {
    return endGame;
}

public static boolean isEndGame() {
    return endGame;
}

public static void setEndGame(boolean endGame) {
    GameTimer.endGame = endGame;
}
Timer timer = new Timer();
TimerTask task = new TimerTask(){
    public void run(){
        seconds--;
        System.out.println("180 / " +  seconds);

       if (seconds == 170){
         System.out.println("170 seconds hit the spot" );
         endGame = true;
         this.cancel();
        }

    } 
};

public void start(){
    timer.scheduleAtFixedRate(task, 1000, 1000);
    isEndGame();
    }   
}

public class GameViewManager {

public void gameTimer() {
     GameTimer timer = new GameTimer();
         timer.start();
     //System.out.println(timer.returnBool());

        if (timer.isEndGame()){
        //gameStage.close();
        System.out.println("test");
       }
      }
    }
