Whoops, you're right Soul. 13 years ago. However, if the pirate that cut his arm off had once pleaded with Z to save his life while Z was an admiral or earlier (since he would not have arrested a pirate while he worked as a training instructor), that pirate would still have been active at least 36 years ago, making that person at least 50 years old if they were a pirate captain then(most pirate captains we've seen have been around 16-20 years old, minimum). And that would place him in the same-ish generation as Roger. And Nada, Buggy and Shanks are part of the generation of pirates after Roger, since they were not captains at that time, just cabin boys or something similar.
