Time zone changes are controversial globally

Some countries around the world have changed time zones to reduce difficulties and confusion related to the time for business people and people, while arguing about the benefits and losses of real-time summer time. In many countries it is not over yet.

Russia, Malaysia, Singapore . have changed time zones, while Australia, New Zealand, USA, Canada and many Nordic countries annually adjust the summer time. Leaders of ASEAN countries once proposed a common time frame in the bloc.

Russia, the largest country in the world, can continue to change the time zone after evaluating the impact of time zone transfers from 11 to 9 from March this year. Aman Tuleyev, governor of Kemerovo province in Siberia, said the time zone difference was meaningless: 'You just came to the city next to you and had to turn the clock down for an hour, then have to turn back when you return. . This causes confusion '.

Even some small-scale protests took place in Samara, the area near Moscow. They think that this change leads to a darker future. The Russian government and scientists are considering the impact of time zone changes with energy saving, health, defense, and communications in five regions to continue to adjust if the pilot area is operational. good use.

Malaysia has changed the time zone many times in history. Malaysia's current time zone is taken according to the eastern region's time zone (GMT + 8). This is considered a political solution to harmonize the western territory with the eastern territory, although up to 80% of the population lives in the western region.

Next, Singapore also changed the time zone in 1981 to reduce the inconvenience of time, specials and trade and traffic over a 1 km long road connecting Malaysia's Johor Bahru City with Singapore's Woodlands town. .

Some countries in the world, especially in the temperate or near-polar regions such as North America, Northern Europe, are implementing summer time conventions by adjusting the clock by an extra hour compared to the standard time around from March to October every year to save lighting and heating energy.

Research by the Department of Transportation Research and the University of London (UK) said that the number of people with traffic accidents is less if an hour in the morning changes to the afternoon. Some countries like Canada, Cuba, Chile, Argentina, Mexico, America . summer time convention to save energy consumption when demand for electricity and gas is increasing.

According to the 2004 socio-economic development report of the Productivity Center (Japan), the implementation of the conventional summer time saves 931 million liters of fossil fuels. However, the report of the California Energy Commission (USA) in March 2007 showed that the implementation of the time to take advantage of sunlight has little effect on the amount of electricity consumed in this state.

According to research results published in New England medical journal (USA), the number of people suffering from heart attacks increased significantly in the first 3 weeks of implementing the country's summer time convention in 2008. Many people complain that This convention changes the bedtime and biological clock, causing them to have headaches and stress when the body has not yet adapted to the new working hours and activities, leading to an increase in traffic accidents and accidents. labor accident.

In the five days after Russia cleared the time zone in five regions, the number of emergency calls for people with hypertension and myocardial infarction in the five pilot areas increased by 11%. The number of suicides in those days also increased by 60%, Russian scientist Sergei Kravchenko said.

Some people's opinions about changing time zones:

Trinh Thi Huong, Hanoi University of Economics - Hanoi National University: I do not support changing time zones because that makes people's biological rhythm changes. I cannot calculate what time zone changes will save the State, just thinking that the life of more than 86 million people will be disturbed.

Nguyen Huu Tu, Institute of Machine and Industrial Tools: For each individual, that change only leads to small changes in habits. Maybe having an hour's work earlier gives us more opportunities to succeed.

Nguyen Van Quang (Central Post 3, Hanoi): If I change it to GMT + 8, I will have to work 1 hour earlier than today and go home 1 hour earlier. Now I go to work at 5am so if I change, I will feel more tired in the morning. However, in the early afternoon, I will have time to make up for sleep, have more time to play sports, and use less electric equipment. I'm not sure about winter yet.

Ha Quynh Nga (Indochina Land): I see changing the time zone to the same time as financial centers, convenient for transactions, air transport, reduce costs due to waiting for reasons of time zone difference. It is good. In addition, I like longer days than nights because I have more time to do things, in the afternoon I go back to eat, bathe and still have time to play.

Ho Bo: Do not know who gave the idea of ​​changing the time zone? Why? Where is savings? The winter is still a short day of long counting, the summer is a long and short night Do you work 8 hours a day if you are a civil servant or work in shifts or work on assigned tasks or because of an individual's passion for work? If you want to coincide with the major stock markets in the region to avoid damage if an economic crisis occurs, simply open the trading floor an hour earlier. (Not to say it is beneficial).
