What sort of timepiece did you use to check for the time? Disney's time is synced to the EXACT atomic time signal and unless you have a watch or some other device that captures that signal and adjusts itself you might be a few seconds off and that makes a major difference when 10,000 other people are trying for the same boarding pass at the same time. I play the boarding pass game frequently when I'm at home, 1,000 miles away from Disney. I have never seen the passes "sell out" before 8 seconds into the hour.
