GMT is being replaced by UTC because UTC is more precise and globally standardized. GMT is based on the rotation of the Earth, which can vary. UTC incorporates International Atomic Time (TAI), offering greater accuracy for international timekeeping.

FAQs & Answers

  1. What is the difference between GMT and UTC? GMT is based on the Earth's rotation, while UTC is more precise and based on atomic time.
  2. Why is UTC preferred over GMT in international contexts? UTC offers greater accuracy and is standardized globally, making it ideal for international timekeeping.
  3. How does UTC affect global communication? UTC provides a uniform time standard that facilitates accurate scheduling and communication across different time zones.
  4. What are the implications of the GMT to UTC switch? The switch enhances precision and consistency in timekeeping, crucial for various industries and technologies.
