I have long thought that "As the world turns" was a reference to give us our units of time to use; Days. Marker, wind the clock, etc would start the timer. Trying to learn comms along this line of thinking, I have looked at deltas, chessboards, news sources, etc. I admit, though that I have been unable to identify a pattern, so my theory is just as likely or unlikely as any other.
Thank you Anon. I will have a look.
