I feel like you set this criteria and then try to set different criteria. Given the above, the machine would show you your future (i.e. you making a sandwich for lunch). So if you want to change that: let's say you would decide to go to McDonald's. So then if you look into the machine again you would see yourself going to McDonald's because that would be the future. It seems to me that the machine would show the future from a given present time, not a future without time, because the whole point is that the future can be changed. If you want to argue that the future cannot be changed and that everything is pre-determined, you are breaking the rules that you initially set.
