However, different time standards in different locations have caused time confusion. In order to overcome this situation, in 1884, various countries held an international longitude conference in Washington, and the participating countries created a universal standard time system-with 180° longitude as the theoretical date line, longitude every 15°, the local time difference is 1 hour .


But not all countries follow such regulations. The spans and borders of different countries vary greatly. It is not realistic to require countries and regions to strictly follow the standard time generated by the time zone. Therefore, for countries such as China, the United States and Russia, which have a huge land area and span multiple time zones, how to set an appropriate time zone is a troublesome matter.


Generally speaking, when a country sets a time zone, it will set the zone time as much as possible according to the agreement to make it suitable for itself. However, the chaos and trouble caused by too many time zones are still inevitable.

In addition, in order to cater for viewers in different regions, Russian TV stations are divided into five versions of Moscow +8, +6, +4, +2, 0, which include Russia's first channel and Russian state television, which is the same to this day.

This appeared

此外,为了迎合不同地区的观众,俄罗斯电视台将莫斯科+ 8,+ 6,+ 4,+ 2、0分为五个版本,其中包括俄罗斯的第一频道和俄罗斯的国家电视台。今天一样。一些电视台要简单一些,只需将+6和+8合并为+7时区,例如文化频道,儿童频道,独立电视台和覆盖全国的其他电视频道。这出现了

If these are trivial matters, then multiple time zones lead to a unified national examination (Russian college entrance examination)


In May 2013, the first Russian language test for the college entrance examination in some areas had not started, and the original questions on the Internet had already flowed out. The survey results show that the candidates are in different time zones which led to the leakage of the test questions"


In 2014, Russia passed a bill declaring that Russia will always adopt winter time after October 26. Prior to this, the All-Russian Public Opinion Research Center recently disclosed a survey on the winter and summer time system, and one-third of the respondents tend to use winter time. After adopting winter time, Russia's time zone was increased to 10.


The vast territory of the United States also has as many as 9 time zones, from the Samoan Islands at the westernmost 11th district to the Atlantic time zone at the easternmost western 4th district. The time used varies from place to place.

Every New Year's Eve, when Times Square starts to celebrate the New Year, people in Los Angeles and Las Vegas may have just finished eating. When flying from the west to the east of the United States, you must not forget to adjust the watch. Even banks and hotels retain the tradition of hanging a few clocks.


Take the NBA as an example. The NBA Finals are scheduled at 9pm on the East Coast (6pm on the West Coast), and the same is true for Western teams at home. People in the east can sit on the sofa and watch the football game comfortably during the evening break, but at this time a large number of people in the west are busy cooking, eating and washing dishes, and watching the game is not fresh anymore.

以NBA为例。 NBA总决赛计划在美国东海岸的晚上9点(西海岸的晚上6点)进行,西方国家队也是如此。东部的人们可以在傍晚休息时坐在沙发上舒适地观看足球比赛,但是此时,西部的许多人正在忙于烹饪,饮食和洗碗,而且观看比赛已经不再新鲜了。

After the fall of the Qing government, in order to facilitate the planning of the national time, the Beiyang government divided the country into 5 time zones in 1918.

After the victory of the Anti-Japanese War, many people returned from Chongqing, Chengdu, Kunming and other places to the regions where the Central Plains time was used.
