Hell-by-Date

A hypothetical kind of life-clock that would show the exact date of death of any evil/Hell-bound individual. This device is still undergoing construction.

A person who is paying a huge price for rent or something might say, "Hey when's my landlord's Hell-by-date?"
And the answer would automatically be, "June 27, 2999."
