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 South 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 a priori reason for placing the South Pole in any particular time zone, but as a matter of practical convenience the Amundsen-Scott South Pole Station keeps New Zealand Time. This is because the US flies its resupply missions ("Operation Deep Freeze") out of McMurdo Station which is supplied from Christchurch, New Zealand.

Famous quotes containing the word time:
“I have only made this [letter] longer because I have not had the time to make it shorter.”
—Blaise Pascal (1623–1662)
“To Time it never seems that he is brave
To set himself against the peaks of snow
To lay them level with the running wave,
Nor is he overjoyed when they lie low,
But only grave, contemplative and grave.”
—Robert Frost (1874–1963)
“It is because the public are a mass—inert, obtuse, and passive—that they need to be shaken up from time to time so that we can tell from their bear-like grunts where they are—and also where they stand. They are pretty harmless, in spite of their numbers, because they are fighting against intelligence.”
—Alfred Jarry (1873–1907)
