International Time refers to the system used to coordinate time across different regions of the world. It is primarily based on the concept of time zones, which divide the Earth into 24 sections, each typically one hour apart. The starting point for these time zones is the Prime Meridian, located at 0 degrees longitude in Greenwich, England. To standardize time further, the Coordinated Universal Time (UTC) is used as a reference. UTC does not change with the seasons, unlike some local times that observe Daylight Saving Time. This system helps facilitate global communication, travel, and trade.
