IBM Z Time Synchronization Implementation Guide

The IBM Z time synchronization solution uses two technologies to ensure precise, consistent, and resilient timekeeping across IBM Z systems; Server Time Protocol (STP) and External Time Sources (ETS). STP is a server-wide facility that is implemented in the Licensed Internal Code (LIC) of the IBM Z® platform. It provides improved time synchronization in a sysplex or non-sysplex configuration. ETS on IBM Z supports standard protocols like Network Time Protocol (NTP), Precision Time Protocol (PTP), and Pulse Per Second (PPS) to keep accurate universal time. This IBM Redbooks® publication is intended for infrastructure architects and system programmers who need to understand the STP and ETS functions. Readers are expected to be familiar with IBM Z technology and terminology. This book provides planning and implementation information for STP and ETS functions and associated software support for the IBM z17™, IBM z16®, and IBM z15® platforms.
