Associate Professor of Distributed Systems
This lecture segment introduces the complexities of physical time in distributed systems, detailing issues such as clock drift, the inherent inaccuracies of hardware clocks, and the mechanisms of Network Time Protocol (NTP) for synchronization across nodes.

This video is part of an 8-lecture series on distributed systems, given as part of the undergraduate computer science course at the University of Cambridge. It is preceded by an 8-lecture course on concurrent systems for which videos are not publicly available, but slides can be found on the course web page: https://www.cl.cam.ac.uk/teaching/2122/ConcDisSys/materials.html
