The chess timer gives you time for the battle, which is only added as long as the battle hasn't ended.
So, if you're given 1 minute for a battle and you spend half a minute on it, then half a minute will be deducted after the battle ends.
Are you sure that's not what you're talking about?
Because there are also long battles. Then it's better to have no timer and 2 minutes :D
