Question 1

What is clock skew?

  • A) The difference in rates of clocks
  • B) The instantaneous difference in time between two clocks
  • C) The divergence from UTC

๐Ÿ’ก Hint: Consider how different time readings can represent skew.

Question 2

True or False: Clock drift can accumulate over time leading to clock skew.

  • True
  • False

๐Ÿ’ก Hint: Think about how continuous drifting affects difference.

Challenge Problems

Push your limits with challenges.

Question 1

Calculate the final clock skew given that Clock A drifts at a rate of 2 ms/s for 3 hours compared to Clock B which is perfectly synchronized.

๐Ÿ’ก Hint: Convert hours to seconds!

Question 2

Propose a synchronization strategy to minimize clock drift in a large distributed system.

๐Ÿ’ก Hint: Think about incorporating both redundancy and regular updates in your strategy.
