Working 9hrs a day for someone else programming his brain to be stuck in a societal matrix day in and day out, making him another cog keeping the machine running with no sense of life.
Unironically I think I get it. It's his visual representation of the days lengths. A small section before the large chunk or the busiest part, and then it splinters off into multiple small and consistent tasks. I think of work like this at least.
By the 7th iteration all timelines will have been converged and consolidated into the final, consummate timeline (for the few who are fortunate enough to survive all prior timeline jumps).
