    IEEE 1588TMStandard for A Precision Clock Synchronization Protocol for Networked Measurement and Control Systems

    Sponsored by the Technical Committee on Sensor Technology TC-9

    IEEE Instrumentation and Measurement Society


    This standard defines a protocol and time-sensitive components enabling precise synchronization of clocks in distributed systems.The protocol is applicable to systems communicating by local area networks including, but not limited to, Ethernet. The protocol enables heterogeneous systems that include clocks of various inherent precision, resolution, and stability to synchronize to a grandmaster clock. The protocol supports system-wide synchronization accuracy in the sub-microsecond range with minimal network and local clock computing resources. The standard specifies how to customize the protocol for specific application domains using a profile. The technology defined by IEEE 1588 is currently being used in the following industries: telecommunications, power generation and distribution, industrial automation, robotics, data acquisition, test and measurement, financial.

    P1588 Working Group Current Activities: 

    Currently the P1588 working group is working on preparing a new edition of IEEE 1588 for publication. The revision was approved by the IEEE-SA Standards Board in November of 2019.  The new edition will be named IEEE 1588-2019, and will be available in early 2020.  


    Further changes to IEEE 1588 will be executed as amendments to the standard, and roll up revisions of approved amendments.  For more detail on the process see the document PAR methodology for IEEE 1588 at  PAR Methodology for IEEE 1588.docx
