Time played counter

It would be interesting to be able to track how many hours we've spent on the game. Previously I know there were websites like Wasted-On-Lol that would check the API and tell players how much time they've spent in game. But as a primarily normal games player being able to only see the time I've spent in ranked games is irrelevant to me. Before the API changes I had over 3k hours in game on my main account alone.
