Oh while solving I didn’t even realize CST is already used, I was just thinking Chicago Standard Time lol. I was thinking Chicago doesn’t do daylight savings and so had their own timezone, not sure who I had them confused with!
Arizona doesn't do daylight savings time. Also their is a province in Canada that is shaped as ⅓ of a sudoku that doesn't do dst, and the home place of some of the best looking turtles
