The places on Earth where the sun is going down in a precise moment, are demarcated by the area in the shade, facing east, as opposite to the area illuminated by the sun, facing west.

From the exposition to the sun of the Globe, we can deduce that Australia is in the middle of the night, while the sun is going down in Tokyo (Japan).
