Walt,
People did not have as much access to time devices in the 60's and often were less precise than people today, who are saturated with time keeping devices (watch, mobile phones, PC's).
12:30 could mean anywhere within 15 mins of that time.
That's silly..... We've been "on the clock" since we became an industrialized nation. On the farm the clock was unimportant..... The sun regulated he work day..... The work day was sunrise to sunset.....
I understand that you'd like us to believe that Whaley paid no attention to the clock.... But in reality he watched the clock very closely. He knew EXACTLY how long it took to travel between points in Dallas.
On a different note....

Question: How many transfers did Lee have? The cops removed one from his pocket at the time of his arrest, and they removed another one from his pocket at about 4:00pm when he was booked.....
