Is there a time difference all over China?

Yes, the time difference in Hangzhou: 0 hours, 0 minutes and 46 seconds, Yuhang: 0 hours 1 minute 12 seconds, Fuyang: 0 hours, 0 minutes 12 seconds, etc.

China's national standard time is Beijing time, which is the time zone that China adopts the international time zone Dongba time zone as the standard time.

Beijing time is not Beijing local time (1 16.4 E), but the local time of East Eighth District (120 E), so the local time of East 120 E is about14.30 minutes earlier than Beijing local time. Beijing is named "Beijing time" because it is located in the East Eighth District of the international time zone, which is 8 hours different from Greenwich Mean Time (UTC) (that is, Beijing time = UTC +8 hours).

China is a vast country, and the time service stations that span five time zones (namely, five time zones of East Five, East Six, East Seven, East Eight and East Nine) must be built in the geographical center, thus generating the Long and Short Wave Award.

Introduction to the division of appeal time zones:

The earth rotates from west to east, and the sun appears earlier in the east than in the west, and the time in the east is earlier than in the west. The difference between eastern time and western time is not only calculated in hours, but also in minutes and seconds, which brings inconvenience to people.

In order to overcome the time confusion, an international longitude conference (also known as the International Meridian Conference) held in Washington in 1884 stipulated that the world should be divided into 24 time zones (East 12 time zone and West 12 time zone). Britain (the former site of Greenwich Observatory) is defined as the central time zone (zero time zone), East 1- 12 and West 1- 12.

Each time zone spans longitude 15 degrees and the time is exactly 1 hour. The last east-west zone 12 spans longitude 7.5 degrees respectively, and is bounded by east-west longitude 180 degrees. The time on the central meridian of each time zone is the time uniformly adopted in this time zone, which is called time zone. The time difference between two adjacent time zones is 1 hour.

For example, the time of China East Zone 8 is always 1 hour earlier than Thailand East Zone 7 and 1 hour later than Japanese East Zone 9. Therefore, people who travel abroad must adjust their watches at any time to keep up with local time.

Set your watch back to 1 hour every time you go westbound (for example, from 2 o'clock to 1). Set your watch forward 1 hour every time you go east (for example, from 1 to 2 o'clock). It is also stipulated that Britain (the former site of Greenwich Observatory) is the prime meridian, that is, the zero meridian.
