The Great Confrontation

I didn't understand Adv's message about the turn lasting the entire 15-20 minutes. Is it okay that no one stops the time during the battle? Or do you mean that the last battle takes so long?

Have you ever noticed that when you pass your turn and the timer shows 1:42, for example, the time on the timer then increases and becomes, for example, 2:35? That is, the opponent left the battle, and the time was recalculated.
Therefore, the battle time is not equal to the real time, that's ONE, and the fact that you can get into a battle for another 10 minutes with the remaining 5 seconds of your turn is TWO.
