we witnessed the "not paying attention to the time" first hand in St. Maarten in November. We were docked across the pier from the Carnival Freedom and watched as it backed out and was turning around,heading out to sea when 3 passengers came running down the pier. It was like watching a wreck, where you dont want to look, but cant help it. There were alot of screams, crying and yelling...the passengers tried to get the harbor pilot to take them out to catch the ship(no go) then they came over to our gangplank and I assume they were trying to make a deal and get on our ship(no go #2)...eventually a pier agent came and got them and drove them off the pier. When the Capt. says to be back by a certain time, we always get back at least an hour before. I will not go through what I saw firsthand. And there are clocks onboard so theres no reason why you dont know the correct time.
