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:
“I think it’s unfair for people to try to make successful blacks feel guilty for not feeling guilty.... We’re unique in that we’re not supposed to enjoy the things we’ve worked so hard for.”

“The well-educated young woman of 1950 will blend art and sciences in a way we do not dream of; the science will steady the art and the art will give charm to the science. This young woman will marry—yes, indeed, but she will take her pick of men, who will by that time have begun to realize what sort of men it behooves them to be.”
—Ellen Henrietta Swallow Richards (1842–1911)
“All civilization has from time to time become a thin crust over a volcano of revolution.”
—Havelock Ellis (1859–1939)
