The point which you choose to miss is that 12:30 channel 2 time is 12:30 Hertz billboard time is 12:30 Powers time is 12:30 Kellerman time is 12:30 Sorrels time. Even if we assume that the Secret service agents explicitly synchronized their watches that day, we still wind up with the fact that 4 independent time sources put the time of the assassination at 12:30, including the channel 2 clock. I could go on and on about the origins of the term "regression towards the mean," and why it's important here, but you seem to have issues with long posts. The TL;DR version is that the agreement of these different clocks strongly imply that the DPD channel 2 clock is running pretty close to standard time. By contrast, what clock, watch, or other time piece can Bowley's watch be compared to? How can we determine the accuracy of his watch? I should mention that Bowley himself has been quoted (in Into the Nightmanre at least, IIRC) that his watch could have been 5 minutes off.

The timeline I have provided earlier (which you most likely reject out of hand) shows by witness statements how the sequence of events is linked in such a way that you simply can not move one part without having to move all the other parts as well.

Here is the time line again, in case you
ignored missed it so far;
Markham leaves her home at "a little after 1" and is en route to the bus stop on Jefferson by 1:06 or 1:07
She only needs to walk one block to get from 9th street to 10th street. The FBI determined that the distance of one block takes about 2,5 minutes to walk. This gets Markham to the corner of 10th and Patton by 1:09:30 at the latest, perfectly on time to reach the bus stop on Jefferson at 1:11 or 1:12.
[Note: if Tippit was killed anywhere between 1:14 and 1:16, Markham would have already been at her bus stop and would not have seen it]1:09 Shooting
Bowley picked up his daugther at school at 12:55 (his words) and is en route to pick up his wife from work. The distance between the school and 10th street takes about 13 to 15 minutes to drive. This gets him to 10th street at 1:10
1:10 Benavides making his call and Bowley arrives
Bowley says (in the video "Hunting Oswald") that when he arrived he noticed something was going on, so he parked his car at a fair distance away so his 12 year old daughter would not see it. He then walked towards the police car, checked on Tippit and then noticed Benavides who could not get the radio of the patrol car to work. It's a fair estimation that this would have taken him around 45 seconds to one minute. During this time Benavides is keying the mic in vain.
1:11 Bowley makes his call, lasting 46 seconds
DPD officers Poe and Jez (squad car 105) wrote in their supplementary offense report that at approximently 1:10 they heard on the radio that a police officer was involved in a shooting at East Tenth Street.
1:12 Callaway arrives at the scene. He only had less than one block to run after hearing the shots, but apparently first
waited until the man with a revolver that came toward him has passed.
1:12:30 After checking on Tippit, Callaway makes his call and hears the ambulance's sirens in the background
Ambulance arrives. Callaway and Bowley help loading Tippit's body into the ambulance
1:12:45 DPD officer Croy is in his car at Zang and Colorado when he hears Bowley's radio call. It takes him no more than
1,5 to 2 minutes to arrive at 10th street. When he arrives he sees Tippit's body being loaded into the ambulance
1:13 The ambulance leaves. The distance to Methodist Hospital takes 2 minutes to drive in normal traffic. With sirens on
it takes less. Ambulance driver Clayton Butler told HSCA investigators in 1977 that "from the time we received the
call in our dispatch office until Officer Tippit was declared dead at Methodist Hospital was approximately four
minutes"
DPD officers Davenport and Bardin are in their car and see the ambulance pass by. They follow it and arrive at the
same time at as the ambulance at the hospital.
1:15 Ambulance arrives at Methodist Hospital and Tippit is declared DOA at 1:15
The DOA time is communicated to the Justice of the Peace who issues an Authorization for Autopsy which gives the
time of death as 1:15.
Davenport writes in his report that Tippit was declared dead at 1:15 and on the form he uses to deliver a bullet
taken from Tippit's body and a button from his uniform he writes in his own handwriting that Tippit was declared
DOA at 1:15
