Simple logic. Sheridan slid forward in time, to wherever he was
at that moment in the future. He didn't just go hopping around
aimlessly; if he flipped 10 days ahead, he'd come into his body at that
point 10 days from now, wherever he happened to be. At that moment, 17
years down the road, he happened to be on Centauri Prime.
