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:
“Everywhere, the ethical predicament of our time imposes itself with an urgency which suggests that even the question “Have we anything to eat?” will be answered not in material but in ethical terms.”
—Hugo Ball (1886–1927)
“Lately, I’ve become accustomed to the way
The ground opens up and envelopes me
Each time I go out to walk the dog.”
—Imamu Amiri Baraka (b. 1934)
“Lest darkness fall and time fall
In a long night when learned arteries
Mounting the ice and sum of barbarous time
Shall yield, without essence, perfect accident.
We are the eyelids of defeated caves.”
—Allen Tate (1899–1979)
