Global timekeeping refers to the system used to measure and coordinate time across different regions of the world. It is based on the concept of time zones, which divide the Earth into 24 sections, each representing one hour of time. The standard reference point for global timekeeping is the Prime Meridian, located at Greenwich, England, which is designated as UTC or Coordinated Universal Time. To maintain synchronization, countries often adjust their clocks for daylight saving time, shifting the time forward or backward by one hour during certain months. This system helps facilitate international communication, travel, and trade by providing a consistent framework for understanding time differences across various locations.
