Continuity: The timer on the antimatter bomb shows just over a third full, but the time they said they have left is 7 minutes, and later "a little over 5 minutes". But when the bomb threat was made, they had about 4 hours before the bomb would explode. According to the timer they would have had only about 15 minutes before the bomb exploded, however this doesn't add up to the time they used to find the bomb.
