It seems that climate and time of day is very much tied in to the mechanics of the simulation. Leads me to believe it's unlikely we will be given much control over it, although I hope I am wrong here we can at least stay in day time as a visual setting or something. Mods will defiantly help on PC-version.

How does the location of a map change its climate and seasons? Longer days, rainier weather, and more snow can all be tied back to the map's location.
