Universal Time

Universal Time (UT) is a time standard based on Earth's rotation, serving as a clock for the world. It reflects the mean solar time at the Prime Meridian (located in Greenwich, England) and is used in astronomy, navigation, and coordinating international activities. UT helps ensure that timekeeping aligns with the natural cycle of day and night across the globe. There are different versions, like UT1 (based on Earth's actual rotation) and Coordinated Universal Time (UTC), which combines astronomical data with precise atomic clocks for high accuracy. Overall, UT provides a consistent reference for global timekeeping.
