Civil time is the system of measuring time that is used for everyday activities and scheduling. It is based on the division of the day into hours, minutes, and seconds, and is typically organized into time zones. Each time zone is a region where the same standard time is used, allowing for coordination of activities across different areas. The concept of civil time is essential for various aspects of society, including transportation, business, and communication. It helps people synchronize their schedules and ensures that events occur at the same time, regardless of location. The use of civil time is standardized by organizations like the International Bureau of Weights and Measures (BIPM).
