You say that the problem arises from the one postulate of special relativity, and not your fantasy? You mean to say "instantaneous transmission" not any old "FTL". If these two persons have relative motion, at two different times, there'd be two different time offsets. Just because you won't spend the effort to learn *anything*, doesn't mean that anyone cares. You've been ignorant of this topic for years now, and have spent *no apparent* effort to fix your obvious problems. Despite this, you seem to feel qualified to make statements based on your ignorance.

So did one exist? Probably not ;-) I don't need to 'payout' to know that. FTL does not violate causality, just sense, 'the pond just looks shallow'. In that sense it's not FTL but the invariant c is not constant, but effectively faster. http://sites.google.com/site/jackokring
