So as discovered yesterday on reddit by someone destiny uses your ps4's internal clock for timer resets. Your able to set the timer backwards only and see previous armour the Xur has had for example. Now if we applied the same logic to bounties would it work? Could we turn back time and get the same bounty 5 times and thus turn in 500rep? And get tones of xp what do you guys think I'm going to give it a go in about and hour when I get home. (Update) went back to reddit and people have said vendors do change as well so this isn't just isolated to xur, here's a link to the thread just in case anyone wants more info, they are making headway over at reddit trying it on things. http://www.reddit.com/r/DestinyTheGame/comments/2iw5hr/how_to_see_all_items_xur_sells_time_change/
