Mary Jo:
When a game has:
Time for game : Time: 1 day, Bonus: 3 hours, Limit: 10 days, no days off

Then it means that:
You have 1 day = 24hours to play the whole game and not the move.
That means: if your opponent plays a move and then 2 hours later you play your response, you will then have 24-2 = 22 hours to play the game.
If your opponent makes another move later and you play after 8 hours(from his response), then you will have 22-8 = 14 hours left to play the whole game.

But that with bonus = 0. With bonus = 3 hours like here, after your move you will have 3 hours added to your time left for the whole game....

Limit = 10 days, just declares that if you play many moves quickly and the bonus is not 0, so your time for the whole game increases, this value can't go above 10 days....

The same exists for your opponent of course.
