Answer 1

Since there is no dedicated method to achieve this behaviour, you could do something like this (you may move it to a subclass PausableTime or so):

void pause() {
    int remaining = dataTimer.remainingTime();
    dataTimer.stop();
    dataTimer.setInterval(remaining);
}

void resume() {
    dataTimer.start();
}

Of course you then need to adjust the interval in your timeout slot again.
