Hours played?

[RelajadoFresco]

Hi, i want to create a custom stat that shows how many hours i ve played in the information box, in the graph section. I have created stats before with your help, but i have no idea how to create this one

Due to the way time stats must be calculated they always break reports down so it's not going to be possible to add a single stat to that info box that will display just hours played.
