Well, direction seem to have less impact to me when I fly then the number of time zones I have to cross that is the real kicker.
On the date line, I would have agree, except, the countries of the world set their date by it, so you are either adding or subtracting a whole day when you cross it, and that has very real effects on jet leg, even if the line itself is imaginary.
