On the Timer: The timer must stay on throughout the whole battle..
On Timeout losses: A player that loses by having all his time run out loses the game. This is only not the case if the player that received the timeout loss can be verified to have suffered a True Disconnection. Rematches are only allowed if there was a True Disconnection.
On True Disconnection: The TD team has a secret threshold of seconds that your timer must be at or above, from the moment you disconnect, for a timeout loss to be considered a True disconnection. If your game is determined to be a true disconnection if you played on Smogtours and contacted a TD before the room expired your game will be recreated up to the point the disconnect happened. It is the responsibility of the player that disconnected to get a TD into the room before it expires.
