You're still making the fundamental error of measuring from infinity towards a specific point.
Any measurement from infinity is undefined. And once again, for the infinityeth time, I'll recommend that you read up on indeterminate form to learn the truth.
In other words, your whole idea about infinite amounts of time not finishing is a red herring: an infinite amount of time does not have a well defined starting point. And a red herring is a fish.
I really don't like the idea of letting sloppy thoughts, such as yours, exist out in the wild. Although truthfully, without duhh, there would be no wild to be tamed, and without the wild, there is no humor.
