Is there a time difference between Yunnan and Shenzhen?

Yes Time difference refers to the difference in local time between the two regions, and there is also time difference between Yunnan and Shenzhen. Local time: With the rotation of the earth, the sun rises in the east and sets in the west in a day. When the sun passes the highest point in the sky, the local time is 12. Therefore, different longitude lines have different local time. The same time used in the same time zone is the time zone (local time on the central meridian of this area), and the same time used around the world is universal time (local time on the prime meridian).
