What I don't understand is why the time disparity issue came up in the first place. Why was it so important for them to have been only out for 30 seconds? Why couldn't Data have just said that the crew was unconscious for a day and not have the mystery?
Did it have to do with their supposedly going through the wormhole or something, therefore it was only supposed to be a short distance? Maybe it's really obvious and I am dumb.
