To the past it is possible to travel by plane
Flight CL32 of Air China took off at 00:08 on January 1, 2022 in Taipei (Taiwan) and landed in Vancouver (Canada) at 5:55 on December 31, 2021.
Changing hemisphere and date is possible thanks to many daily flight itineraries that go back in time by turning backwards.
The international date change line It is an imaginary terrestrial surface line drawn over the Pacific Ocean and close to the 180 ° meridian. And going from one side of the line to the other implies changing the date, exactly one day.
Time Zones and Universal Time
The coordinated universal time system was designed by an international group of experts from the International Telecommunication Union. Since it was desired that the same acronym should be used in all languages, it was decided by UTC, an intermediate solution between English Coordinated Universal Time CUT and French Coordinated universal time TUC.
One time zone It is each of the parts in which the earth’s surface is divided by 24 equally spaced meridians and in which the same schedule is conventionally governed. 24 zones are equivalent to 24 hours, numbered from 0 to 23 hours.
In this episode Felix Riaño (@locutorco) shares curiosities of these trips to the past, the story of how all this order of time zones and universal time arose.
Countries with single and multiple time zones
Currently, all nations use standard time zones, but not all apply the concept as it was originally conceived. Several countries use deviations of half an hour or a quarter of an hour from the standard.
China and India, for example, use a single time zone despite the extent of their territory far exceeding the ideal 15 ° longitude for one hour.
For ElSiglo21esHoy.com legal time is just a convention. And although you can gain or lose hours and days by traveling in one direction or another on earth, as happened in the book Around the World in 80 Days by Jules Verne, what matters in the end is whether the time has elapsed for you. fast (like when you live intensely or have a lot of fun) or slow (when you are deeply bored).
