What time is it? Sure that well played anyone respond to that phrase interrogatoria either ask it to alguena. Give the reply to that question so common is not so easy. As regards this question almost 450 years ago went wrong which worried many people. Almost three years he travelled on a ship the first expedition around the world. The issue in question was directed by Magellan who died during navigation. The journey undertaken five ships of which only the ship Victoria returned to the city of Seville on September 6, 1522.
In this boat returned only 18 people, weak, sick and thin as skeletons. It should be noted that the journey was undertaken by 258 people. Immediately from the ship 18 persons mentioned carrying lighted candles, reeling from weakness, headed to the Cathedral of Seville to apologize to God of the sins that had been unwittingly during the long journey. What sins would have Unable to commit? Way back the sailors of the ship Victoria landed at the Cape Verde Islands for reservations of provisions and water, they realized that it was then in the Islands Thursday, but in Victoria according to the log-book was Wednesday. Day that the Victoria landfall in Seville does not fit doubt that in the log-book had been wrong in a day. They had left one day without counting. It turned out that the sailors had been held all religious holidays a day before, so, in all Church asked forgiveness to God for their sins.
Strangely it seems then Mariners not had been wrong, since all dates were mentioned in the log-book. Where was the mistake? The Earth gives one full turn of the West to the East in a 24 hour period. The Victoria Mariners travelled in the opposite direction, i.e. from East to West. The three consecutive years, which lasted for navigation, of the victory gave a complete revolution around the Earth, but in the opposite direction to which moves the planet. Thus, during the three years they gave one lap less than our planet, and that was the day that lacked. If the expedition made the trip in the same direction of rotation the Earth, i.e., from West to East, had happened the other way round, i.e., they had turned one rather than the Earth. When the distances are small, the time difference, is not taken into account since this is small. But travel around the world makes us keep an eye on the time and setting time. For example, if at 12 on the night of December 31 we refer a message via electronic mail from the city of Vladivostok to Moscow, the message you receive in the capital of Russia at 7 pm on December 31. That is, the message receive 5 hours before being sent.
