Precision Time Protocol (PTP), AKA the IEEE 1588 Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems has been in existence since 2002. It is now in its third version as IEEE 1588-2019. PTP is capable of sub microsecond accuracy, and as such, has become very important for enabling compliance with recent, more stringent time synchronization accuracy regulations in the banking and finance industries. IBM introduced support for PTP on IBM Z with the z15 in May 2020. PTP provides a new, extremely accurate to UTC external time reference for IBM Z Server Time Protocol (STP) environments. PTP will play an increasingly important role in these STP environments. This session will be an introduction to the PTP standard and its technology. The speaker is the IBM Z Timing Architect, represents IBM in the IEEE 1588 Working Group, and helped draft the IEEE 1588-2019 standard.
