UTC stands for what?

UTC stands for what?

• A. Universal Time Coordinated
• B. Greenwich Mean Time
• C. International Atomic Time
• D. Coordinated Universal Time

Answer: (D)

UTC stands for Coordinated Universal Time. It is the global time standard used to synchronize clocks everywhere, combining the stability of atomic time with occasional leap seconds to stay in sync with the Earth’s rotation. Greenwich Mean Time is an older term tied to the Earth's rotation and now mostly a time zone reference, while International Atomic Time is the pure atomic time scale without leap seconds, so it differs from UTC.
