It's a pity you allowed yourself to be distracted from this point.
Martin and John fail to realise that "real time" is utterly meaningless in this case.
There is no way to corroborate that any watch/clock is synchronised with whatever is to be regarded as the representation of "real time" [the USNO master clock according to John].
No Unassailable Fact or Absolute Truth can be determined from the available evidence regarding the Tme in this case, we are in the subjective realms of Common Sense and Reasonable Doubt.
There are three Times to consider:
Police Time - the timestamps called out by the police radio dispatchers on channels 1 and 2
Dealey Time - the clocks/watches in Dealey Plaza and any witness evidence regarding times
Patton Time - the clocks/watches around Patton and 10th, plus any witness evidence regarding times.
The events in Dealey Plaza are connected to those around Patton and 10th by the police radio. An example would be Bowley's call on the radio in Tippit's car being heard by Hill, Owens, Sawyer and Alexander stood in front of the TSBD building.
Martin's argument is that there is a 5 minute discrepancy between Police Time [channel 1] and Patton Time.
If this is the case there must be a similar 5 minute discrepancy between Police Time [channel 1] and Dealey Time.
However, the available evidence supports the view that no such discrepancy exists.
The events in Dealey Plaza are connected to those around Patton and 10th by the police radio. That would be the case if the recordings of the police radio were indeed continuously, which they were not. Also not to be ignored is a sliced tape at 1:12:15 that nobody knows how long the gap really is.

There are three Times to consider:Actually, there are a few more times to consider;
1. The time it took Markham to walk to block to take her regurar bus on Jefferson
2. The time Bowley's daughter's school bell rings
3. The time needed for Bowley and his daughter to drive 6.3 miles to get from Singing Hills to 10th street
4. The time Callaway needed to run down Patton to 10th street (less then one block)
4. The time the doctor at Methodist hospital declared Tippit D.O.A. at 1:15
5. The time Officer Davenport reported that same time of D.O.A. in two separate reports
You see, there is a sequence of events which can be linked to eachother.
After Markham left home only needed to walk one block of roughly 400 feet to get to 10th and Patton. When she arrived there she stopped to let a couple of cars pass by. She then saw a man walking east followed by a slow driving police car. Less than 30 seconds later shots were fired. Callaway heard those shots and then saw a man running towards him on Patton. When the men turned onto Jefferson, Callaway ran less than one block to the scene of the shooting. When he arrived, Bowley was already there and had already made his 48 seconds long radio call.
Now, here's the thing; Bowley said he picked up his daughter at school at 12:55, but let's say that he was there and waited for the girl until the school bell rang at 1:00. He then went to pick up his wife from work, on 9th street. He used Marsalis Ave and drove a verifiable total of 6.3 miles, which at a normal speed of 30 miles per hour would have taken him 12 minutes. We know for a fact that he arrived between Tippit being shot and Callaway arriving on the scene. He said he looket at his watch and it said 1:10, but let's for argument's sake say that his watch was off by 2 minutes and it really was 1:12. Taking in consideration that Bowley needed 48 seconds to make his radio call, it is a fair assumption that he probably arrived at the scene around 1 minute after the shooting. Markham was there roughly 1 or 1,5 minutes before the shooting after walking one block of 400 feet in about 2,5 to 3 minutes. It's not 100% perfect, but the time Markham said she left home, at 1:06 or 1:07 fits perfectly into this time line.
So, for Tippit not to be shot at around 1:10, this entire block of evidence needs to shift in time by several minutes, resulting in Bowley needed at least 17 minutes to drive 6.3 miles and Markham being at the scene at the time she was supposed to be at the bus stop on Jefferson to get her regular bus. Very unlikely.
