A: Hey! This train is late! I've been waiting here since seven.
B: Which train, Madam?
A: The seven-twenty-train to Maryland.
B: The seven-twenty? I think there's a mistake, Madam.
A: A mistake? My timetable says: Maryland train - 7.20.
B: Oh, no. The Maryland train leaves at twenty to seven.
A: Twenty to seven?
B: Yes. They changed the timetable at the end of February. It's the second of March today.
A: Oh, dear! May I see the new timetable? What does it say?
B: It says: Maryland train - 6.40.
A: So the train isn't late. I'm late.
