I disagree. OP is looking to track "
the game's timer when playing" specifically on the "
playing game screen" such as a countdown as seen in his screenshot. Although you could technically use the raw Timer() and resetTimer() approach, you'll have
much less control than you would by simply tracking it via a few user variables. Also if Timer() is being used for anything else in the app, resetting it strictly to track the game play time can have undesirable consequences elsewhere.
