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
