Passing of time, how does it work?

[Mister Cat]

I haven't bought this game yet but it's been on my wishlist for a while.
I've read about it here and there and am slightly confused about the passing of time in the game. I've read that it passes faster when you're 'at home', and that it passes when you're not playing the game... so my question is, it passes even when your computer is completely off? How does it do that? Just take a timestamp from your save and a timestamp from your computer and do the maths?
Just a point of curiosity for me,
Cheers

Hey! Basically the game plays itself *every time*, even when your PC is off, even if you will uninstall it, considering you've started playing it. The time passes by just like in real life but at home it will pass quicker depends on some modifiers. However there's a system to make game true hardcore for some of us (including me) when you can turn off those modifiers and play it normally (second per second) all the time. But that's if you want to. It is easy to do and it's in-game option.
