Huh. But when I rewatched yesterday, they said "30 years ago", when the Earth/Minbari war was just a decade ago as constantly said in the s1 credits!
ETA: it having been 30 years is also why initially they all declare it can't possibly be Jha'Dur, since the woman would be so much older, and why even before Franklin checks her serum her state of arrested age is seen as proof of her claim. If the Dilgar war was after the Earth/Minbari war, her not having aged would hardly be a surprise!
