Who's to say the Hertz clock represents "real" time? We don’t know how or when it was calibrated.
What is "real" time in this instance?
What is the source that all clocks and watches should be measured against.
The best I can offer is when four independent sources confirm the time of the assassination as 12:30pm we can safely assume this is indeed "real" time.
You don’t know that they’re independent. For all you know, the channel two dispatcher set his clock to match the Hertz clock that morning and that Powers looked at the Hertz clock and misremembered it at looking at his watch. Greer is hearsay.
I present a solid argument for synchronising the timestamp of the DP tapes with "real" time, backed up with multiple evidence and all you can do is offer up is these half-baked fantasies? It's beyond desperate.
Why not just say that I don't know if Powers, Greer and the dispatchers met up at the TSBD before everyone else was awake and all set their watches/clocks to the Hertz clock?
I can't prove that didn't happen.
Does this ridiculous fantasy cast doubt on whether these are independent sources?
Only in your mind.
The problem you have is that these four independent time "sources" corroborate each other. I am confident it's something that would be accepted as solid evidence by anyone with a grain of common sense.
Besides, the 4 independent sources confirming that Tippit was shot several minutes before 1:15 don’t seem to impress the WC faithful, so why would this?
This argument is so weak you should be embarrassed.
Not even a little bit. Just because they both announce a description doesn’t mean both did it immediately or at the same “real” time.
The point was about synchronising the two channels with each other.
Nothing to do with "real" time.
Both dispatchers finish their descriptions with the timestamp 12:45(pm) confirming, beyond doubt, that channels 1 and 2 are synchronised at this point.
Your misrepresentation of this point once again reflects a certain desperation on your part.
It is unequivocal that both channels are synchronised at this point.
