If the two places are at the same latitude, and the difference between east longitude 1 16 and east longitude 106 is 10 degrees, the corresponding time difference is 40 minutes, that is, the sunrise and sunset time between the two places is 40 minutes, and the sunrise and sunset are 40 minutes earlier than east longitude16 degrees. Existing conditions that are not at the same latitude cannot be compared.
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 meridians 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 meridian of 0 degrees).
Influence of time difference
1, affecting international tourism
Jet lag will affect international tourism. Tourism is an important way for people to understand different cultures and customs. However, due to the time difference, tourists may feel uncomfortable, which will affect their experience and health. In order to avoid this situation, tourists need to adapt to the time difference of the destination in advance and adjust their itinerary to better adapt to the local pace of life.
2. Affect international academic exchanges.
Jet lag will also affect international academic exchanges. Academic exchange is an important way of academic research and cooperation between different countries, but due to the time difference, scholars may miss important academic conferences and lectures. In order to solve this problem, scholars need to know the time difference of the destination in advance and adjust their itinerary in order to participate in important academic activities.
