What is the explanation and difference between Beijing time and astronomical time?

Astronomical time (depending on the ecliptic of the sun) is the time for fortune telling, while the time recorded in ordinary people's minds is the clock time, that is, the average solar time in the artificially set standard time zone. If you were born at the beginning and end of a certain time, you will often make mistakes because of "depending on the sun time difference".

Beijing time is the standard time for China to adopt Beijing Dongba time zone. Beijing time is not Beijing time (1 16.4), but local time 120.

Because Beijing is located in the East Eighth District of the international time zone, it is 8 hours different from Greenwich Mean Time (Universal Time) (that is, Beijing time = Universal Time +8 hours), while China's east and west span 5 time zones (that is, East Five and East).

Six, East Seven, East Eight, East 95 Time Zone) The time service station must be built in the central area, thus causing the broadcast of long and short waves of "Beijing time" not in Beijing, but in Pucheng, Shaanxi.

The time service department of the National Time Service Center of Chinese Academy of Sciences in Pucheng, Shaanxi Province is responsible for releasing Beijing time (China Standard Time).
