Countries that use daylight saving time, 9 a.m. local time, what is his daylight saving time?

Toronto is divided into two seasons of winter and summerWinter time: early November Early March, 9 a.m. in Toronto 10 p.m. Beijing Daylight Saving Time: March November, 9 a.m. in Toronto Beijing 9 p.m. Due to the different longitudes and local time of countries and regions in the world, it will be divided into different time zones.

The official division of time zones, which includes 24 time zones, each represented by an English letter. A time zone is divided every 15° longitude, with one exception, each time zone has a **meridian; For example, GMT belongs to the "Z" zone, so it is usually followed by the suffix "Z" (colloquially "zulu"). In order to overcome the confusion of time, an International Longitude Conference (also known as the International Meridian Conference) held in Washington, D.C. in 1884, stipulated that the world should be divided into 24 time zones (12 time zones in the east and 12 time zones in the west).

The United Kingdom (the former site of the Greenwich Observatory) is defined as the Middle Time Zone (Time Zero Zone), East Zones 1-12, and West Zones 1-12. Each time zone spans 15 degrees of longitude and the time is exactly 1 hour. Finally, the 12th East and West Districts each span longitude degrees, bounded by 180 degrees east and west longitude.

The time on the ** meridian of each time zone is the time uniformly adopted in this time zone, called zone time, and the time difference between two adjacent time zones is 1 hour. The calculation method of time difference: the subtraction of the standard time (the number of real-time zones) of the two time zones is the time difference, and the time when the value of the time zone is larger is earlier.

For example, China is the East 8th Zone (+8), and the East of the United States is the West 5th Zone (-5), the time difference between the two places is 13 hours, and Beijing is 13 hours earlier than New York; If it is a period when daylight saving time is implemented in the United States, the difference is 12 hours.

9 a.m. standard time and 10 a.m. daylight saving time.

In summer, mornings dawn early, and daylight saving time is an hour earlier.

Daylight saving time was abolished in '87, when China was poor, so in order to save energy, people worked for an extra hour during the day and rested early at night.

The place in China is too big, the latitude gap is large, and the time difference is large, nearly 5 hours. And most of the peasants in China have no sense of time, and live this life of rising and rising at night.

Be. Daylight saving time, also known as "daylight saving time" and "daylight saving time", is a system that artificially sets local time in order to save energy, and the uniform time used during the implementation of this system is called "daylight saving time". Generally, in the summer when the morning is early, the time is artificially advanced by one hour, which can make people get up early and go to bed early, reduce the amount of lighting, so as to make full use of light resources, so as to save lighting electricity.

The specific rules of daylight saving time vary from country to country. At present, nearly 110 countries around the world implement daylight saving time every year.
