Probably seems unfair, but the tournament clock may have read 3:00...just playing devils advocate here. The world doesn't unfortunately revolve around the time on your personal cell phone. It's a judgement call really, but you probably should have been there 5 minutes early just to be sure. Next guy could have shown up 5 minutes later and pointed to his watch and claimed to be on time also....I've seen it hundreds of times at running events and such where athlete's disagree with the official time stating that their wristwatch proves they ran the course faster than their posted time... To be fair the tournament should have had an "official" clock they went by to determine the cut-off...
