You have to go to the clockfags thread and read there to get the full story.
I saved a couple of the graphics from when the original clockfag shared their discovery. In Q's posts there was this idea of 43 known connections. This clockfag made a list of the 43 connections. They started on 1/20/2018 at 15 minutes, and went to March 20. I can't explain it, you would have to find the original post in the clockfag thread.
The clockfag also shared a graphic of what they called a map of the 43 connections. It looked like a spiderweb sort of, had all the connections on what you might call spokes, each spoke had a stack of 6 connections. You turn this, thus winding the clock, and it matches posts up with dates. It really is ingenious, and Q has never said it was wrong. I truly think the Q group wouldn't let us fuddle around with a fucked up clock, surely they'd tell us if it was wrong.
