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 American is said to become full-flavored, and in time a most all-round man, through the polish which Europe can impart.”
—M. E. W. Sherwood (1826–1903)
“People get a bad impression of it by continually trying to treat it as if it was a bank clerk, who ought to be on time on Tuesday next, instead of philosophically seeing it as a painter, who may do anything so long as you don’t try to predict what.”
—Katharine Whitehorn (b. 1926)
“The glorious dream of full father involvement in infant care will not become a widespread reality overnight. But it can happen, and it eventually will happen,... A lot of progress may take place in a short period of time if we just lighten up, step back, and give the guys a decent chance.”
—Michael K. Meyerhoff (20th century)
