Anons theorizes one-to-two days from now, which will be 10:[57] & 10:[58] Qclock timse, could be the "11.3 Marker" (well, one of a few, Kevin would argue).
Yesterday was 10:[55]pm (both clock hands essentially on 11), [55] is AT 11 on a clock, plus [03] = "11.3 Marker" at 11:58, Sept 15? It is 2 minutes shy of 11:00pm Qclock time.
Perhaps straddling [57] and [58] offers the best of both worlds, in that [57] is minus [03] from 11:00pm precisely.
Or the Qclock is just the biggest damned wasted of time this anon has committed to in this particular one thirteenth of anon's life. Now… imagine a QClock image posted here with many arrows, circles and drops looking vaguely like a sign of intelligent life. Kek.
Oh wait, maybe there's a YT video with a related thumbnail… meh… close.
