Final answer:
International (military) time, also known as Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT), is a 24-hour time system used globally for military operations, international radio broadcasts, and air traffic control systems. Traditional time, or local mean time, is based on the position of the Sun in the sky and uses a 12-hour clock with the AM/PM system.
Step-by-step explanation:
International (military) time, also known as Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT), is a 24-hour time system that is used globally for military operations, international radio broadcasts, and air traffic control systems. It is based on the local time at 0 degrees longitude, which is the prime meridian in Greenwich, England. In UTC, time is measured in zero- to 24-hour periods, as opposed to the AM and PM system used in traditional time.
Traditional time, or local mean time, is based on the position of the Sun in the sky. It is the time system used by most countries for daily life and commerce. Traditional time uses a 12-hour clock and the AM/PM system to indicate morning and afternoon/evening hours.
For example, if it is 1500 hours UTC, it would be 3:00 PM in traditional time.
