See, that doesn't make sense. Do you know the numbers from yesterday's jackpot? What about 3 months and 2 days ago's winning numbers? The only way that question would work is if they somehow knew the numbers which seems very unlikely unless that was their purpose in going back in time. Or I guess it would work if they lied and made up numbers, but why would anyone do that when they'd know they would be extremely unlikely to get away with it.
