Restart Runnable Variables Android

I want to do something that i am not sure can be done, and so far i haven't found any good answers to my question.

Here is my situation:
- I have implemented Timer as a Handler that has Runnable that is calling itself every 1s.
- I need now to implement a method like Timer.restart() that can restart my Runnable's params.

Here is my code so you can see it, and better understand what i have tried to achieve

private Runnable rStartCPRTick = new Runnable() {
    public int seconds = 0;
    public int minutes = 0;
    public int hours = 0;

    @Override
    public void run() {
        if(++seconds%60 == 0) //increases the time by one second
            if(++minutes%60 == 0)
                hours++;
        mActivity.updateCPRTime(formatHHMMSS(hours,minutes,seconds));
        mStartCodeHandler.postDelayed(this,1000); // tick again in 1s
    }

    public void restartCPRTick(){
          seconds = 0;
          minutes = 0;
          hours = 0;
    }
};

My runnable, i want to be able to call resetCPRTick() from outside Runnable and then call run that starts from the beggining.

Is such thing possible?

Thanks!!
