228 views

GMT was renamed to UTC to achieve universal standardization of time. While GMT is based on the Earth's rotation, UTC (Coordinated Universal Time) is based on atomic time, providing greater accuracy and removing the inconsistencies caused by irregularities in the Earth's rotation. This helps in synchronizing time internationally for various applications including aviation, computing, and telecommunications.

FAQs & Answers

  1. What is the difference between GMT and UTC? GMT is based on the Earth's rotation while UTC is determined by atomic time, providing more precision.
  2. Why is UTC important for technology? UTC is crucial for synchronizing systems across the world, making it essential for applications in aviation, computing, and telecommunications.
  3. How does UTC improve timekeeping accuracy? UTC improves accuracy by eliminating inconsistencies that arise from the Earth's rotation with a more stable atomic clock reference.
  4. When was GMT officially renamed to UTC? GMT was renamed to UTC in 1972 during the adoption of Coordinated Universal Time as the new standard for global timekeeping.
