In this video, I explain Cristian’s Algorithm, one of the simplest and most understandable techniques used for clock synchronization in distributed systems. After introducing NTP, atomic clocks, and the hierarchical structure of time servers in the previous part, this video focuses on how a client actually computes the correct time using Cristian’s method. You will learn what Round Trip Delay (RTT) is, how to calculate Correct Time, and why we divide RTT by 2. I also demonstrate each step with clear examples, including cases where the clocks are synchronized and unsynchronized. The video highlights important assumptions of Cristian’s Algorithm—such as symmetric network delay and immediate server response—and explains why this method does not calculate clock offset and does not consider server processing time, which may lead to small approximation errors. Finally, I compare NTP vs Cristian’s Algorithm to show the difference in accuracy, timestamp usage, and real-world application. This video is ideal for students studying Distributed Systems, preparing for exams like GATE or UGC-NET, or anyone who wants a simple and clear explanation of clock synchronization.

Hi, my name is Amit Sagu, I make easy-to-understand videos on Computer Science concepts, Programming, and Engineering topics to help students learn better and faster. With my experience in teaching and research, I aim to simplify complex technical subjects like .NET, Python, Machine Learning, and Distributed Systems — so anyone can learn them with confidence!.
