If the WORLD establishes an exact spot and an exact date and time, it does not matter what time but I would assume a date near the current date would make the most sense. This date and time is known world wide and it is the set place and time a person from the future must arrive to prove that time travel into the past was achieved. If said person does not show then we know the entire race was destroyed before we advanced far enough or we did not achieve time travel into the past, ever.
