Steam hours hack

So my friends, I would like to have a hack that can change my hours played of CS:GO. is it possible? if yes how

There isn't a way to directly edit your hours i would recommend not bothering with it and einther play the game alot or afk in a idle server.

Steam Achievement Manager (gib.me/sam/), I believe, is able to change hours played. ~~ Be careful using that, though ~~

I don't think it can do this.
However you can use it to idle multiple games at once to get hundreds/thousands of hours played in the last 2 weeks (by opening multiple games at once).
