Updates to information and messages for the Enhanced Accuracy TLV are provided in this amendment to IEEE 1588-2019. This amendment also clarifies the operation of the best master clock algorithm (BMCA), provides a new annex about the default BMCA, corrects errors in the text, and clarifies unclear passages.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
P1588.1
Standard for Client Server Precision Clock Synchronization Protocol
This standard defines a simple and precise time transfer protocol called the Client Server Precision Time Protocol (CSPTP). CSPTP uses Precision Time Protocol (PTP) messages defined in IEEE Std 1588, to take advantage of timing support in network switches and routers. Therefore, CSPTP can achieve time transfer accuracies comparable to what can be achieved using PTP. However, CSPTP is logically isolated from PTP, and therefore can coexist with existing PTP networks. CSPTP allows clients to request timing information from any CSPTP server and allows the servers to operate without keeping state information on clients.
P1588c
IEEE Draft Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems Amendment: Clarification of Terminology
This standard is an amendment of IEEE Std 1588™-2019. Updates to various sections to correct text, make clarifications, and other improvements are provided in this amendment.
P1588f
Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems Amendment: Enhancements for latency and/or asymmetry calibration
This amendment enhances support for latency and asymmetry calibration, and also provides informative text related to these enhancements. It corrects errors in the text and clarifies unclear passages.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
