6:00 APM or PAM?= if u were on the equator,the 1/2 day spent spinning in the same direction as the earth was rotating around the sun, ur speed would be faster & the time would slow down. The other 1/2 day ur speed would be slower as the earthspin is going opposite & time would speed up. At 6am & 6pm , the time/speed factor would be 0 as deccelaration changes to acceleration of the earth's rotation.
If the Sun is up, it's day time. If it's pitch black, it's night time.
Good Question.In the summer at the poles, you could make a perfect sundial. You would just have to know how to orient it. In the winter, of course, your sundial would be pretty much useless.The time zone, however, would be arbitrary as you would have 24 hour sunlight in the summer, and 24 hour darkness at night, so since there are many British on the board, one might as well arbitrarily choose Greenwich Time.The North Pole is over water, and the ice tends to drift, so one could not make a permanent North Pole facility as it would eventually drift away from the pole.The South Pole, however, is in a fixed location. The Amundsen Scott South Pole Station is an American research facility located at the South Pole. With that in mind, one might be tempted to choose one of the several time zones in the USA, for example Eastern Standard Time, or Alaska Standard Time. Oddly, I wouldn't have guessed it, but they actually use New Zealand time at Amundsen Scott.A unique way of defining the clock might be to define noon as being the summer solstice, and midnight as the winter solstice, and divide the hours and minutes of a day as the portions of a year that the rest of the world experiences.

Thanks for this CZARCAR.....gosh !!..one can get dizzy the equator !...but the equator does have time zones doesn't it ?..unlike northy pole and southy pole ?
