While that could be added, the actual details are a bit difficult without compromising realism a lot (in my opinion), like would you experience the day/night cycle during a single swimming around as a cell sessions (which is planned to last like max 5 minutes) or would the day/night change at some interval when going to the editor (which represents 100 million years in the cell stage)? So there are troublesome time differences with day/night. I can kinda tolerate us slowing down environmental changes like ice ages and things to fit the editor cycles, but seasons as well as day/night cycle seems much more difficult to fit in.
