Time
In most places on Earth, local time is determined by longitude, such that the time of day is more-or-less synchronised to the position of the sun in the sky (for example, at midday the sun is roughly at its highest). This line of reasoning fails at the North Pole, where the sun rises and sets only once per year, and all lines of longitude, and hence all time zones, converge. There is no permanent human presence at the North Pole, and no particular time zone has been assigned. Polar expeditions may use any time zone that is convenient, such as Greenwich Mean Time, or the time zone of the country they departed from.

Famous quotes containing the word time:
“The greatest part of a writer’s time is spent in reading, in order to write; a man will turn over half a library to make one book.”
—Samuel Johnson (1709–1784)
“What a phenomenon it has been—science fiction, space fiction—exploding out of nowhere, unexpectedly of course, as always happens when the human mind is being forced to expand; this time starwards, galaxy-wise, and who knows where next.”
—Doris Lessing (b. 1919)
“That Time can never mar a lover’s vows
Under that woven changeless roof of boughs:
The singing shook him out of his new ease.”
