 CONT: In the opening scene (in which the congressman is killed) the  time is given as 0645 hrs (6:45 AM). Later When the congressmans  car is being recovered from the lake, the time is given as 1507 hrs  (seven minutes after three in the afternoon). But the position of  the sun appears to be virtually the same for both scenes. Plus the  TV reporter announces the murder took place something like "an hour  ago" or words to that effect.
