The accuracy of a clock depends on its type. Atomic clocks are among the most accurate, with deviations of less than one second in millions of years. In contrast, quartz clocks may drift by a few seconds per month. Always refer to the clock's specifications for exact accuracy details.

FAQs & Answers

  1. What is the most accurate type of clock? Atomic clocks are the most accurate, with deviations of less than one second over millions of years.
  2. How often do quartz clocks drift? Quartz clocks can drift by a few seconds per month, making them less accurate than atomic clocks.
  3. What factors affect a clock's accuracy? Factors include the type of clock, environmental conditions, and the manufacturers' specifications.
  4. Are there any clocks that do not require calibration? Some atomic clocks require minimal calibration due to their high accuracy, while most other clocks require regular calibration.
