Time zones in America

Why does America have several time zones

If America is every one country, why has actually it been separation into several various time zones? as you may have actually noticed, America is a super huge country. Well, big compared to mine anyway.Time zones were created by train stations, that would each have their own clocks at the end of the 1800s. Yet this made it difficult to name: coordinates schedules. The original solution was to have actually 100 rail time zones. But we instead determined to do time zones for everyone, not just the trains.Because America is for this reason big, having actually one nationwide time zone will median that it it s okay dark incredibly early in some parts. Yet stays light all day in various other regions.

Generally speaking, America is rather judicious with its time zones. But there space some places where time zones will make friend raise a few eyebrows.China is a big country. However, they prefer to keep the whole nation in the same time zone. This reasons several problems, especially at the China/Afghanistan border. Sometimes, you can cross a border and be set back or front by one hour. But if you walk from Afghanistan to China, you will jump front by 3 hours.

China’s insistence on having one time zone because that the entirety country causes problems in Tibet. Over there, they periodically don’t see daylight until 10 am. Although they do have a regional time, the unofficial and not recognised.In the USA, some parts of Arizona have daylight to save time, and also others do not. This can reason you to change time zones several times in one roadway trip.

This go to display that time zones space as much cultural as they are geographical. The ideal example of this would certainly be China. In an ideal world, they would certainly realise lock a large country that requirements to be separation up into various time zones. However they don’t, and also so, the time zones need to bend around them.And when you throw “daylight savings” right into the mix, you gain even an ext confusion.

What is GMT?

Several time in the article, we’ve pointed out GMT. Yet what go this mean?GMT means Greenwich mean Time. That the solar time measured indigenous the imperial Observatory in Greenwich (which is in London). Return it’s been the basis of all time because that a long time, it does have actually problems because it’s calculation differently. Because that example, some can say the midday is as soon as the sun is in the center of the sky. Others would certainly say the work starts when the sun rises.

For this reason, UTC is now the time that’s provided as the base for all various other times.
