I think you are not right. In this test the time difference between two airports is exaclty 5, and the flying lasts 2 hours. So, the first difference ~ -3 hours, and the second one ~ 7 hours.

It's true))
There is a inconsistent problem situation. They should write date of flight.
Sorry for my english.
