	The problem is once you drag relativity into this you have to ask "jump takes 7
days" according to whom? The person in jump, the person in the starting system,
or the person in the ending system? The relative velocity of the person in jump
to the starting and ending system is very important.

	Now one of the solutions to the conflict of "FTL, Relativity, Causality pick
two" is to assume Jump Space is a fixed frame of reference. Like you do above.
And that breaks the using Jump Space as Time Travel.
