As you can see, there is a bunch of GUI stuff in the upper-righthand corner of the screen: time indicator, money counter, date, time and other.
There are also two small icons. Directly below the date, "Sun. 14", there is an icon defining current weather on the left. As you can see, it indicates that it is snowing.
