 How do moon inhabitants tell the time of day?
The shadow line between day and night could be seen from the Moon to be drifting across Australia. Evans, who had no watch, thought of the time as a quarter after Australia. Morning to him had no meaning at all, but he thought in the strictest sense that it would be morning on the Moon for another week. It was used mostly, from sun-up to sun-down, to supplement the nuclear power plant. All of these needed water to form, and their existence on the Moon puzzled him for a while. The sun rose to the meridian slowly. The people on Earth saw the full moon set about the same time that the sun rose.
