Abstract: A protocol is provided in this standard that enables precise synchronization of clocks in
measurement and control systems implemented with technologies such as network
communication, local computing, and distributed objects. The protocol is applicable to systems
communicating via packet networks. Heterogeneous systems are enabled that include clocks of
various inherent precision, resolution, and stability to synchronize. System-wide synchronization
accuracy and precision in the sub-microsecond range are supported with minimal network and
local clock computing resources. Simple systems are installed and operated without requiring the
management attention of users because the default behavior of the protocol allows for it.
Keywords: boundary clock, clock, distributed system, master clock, measurement and control
system, real-time clock, synchronized clock, transparent clock

IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of
the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus
development process, approved by the American National Standards Institute, which brings together volunteers
representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of the
Institute and serve without compensation. While the IEEE administers the process and establishes rules to promote
fairness in the consensus development process, the IEEE does not independently evaluate, test, or verify the accuracy
of any of the information contained in its standards.
Use of an IEEE Standard is wholly voluntary. The IEEE disclaims liability for any personal injury, property or other
damage, of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly or indirectly
resulting from the publication, use of, or reliance upon this, or any other IEEE Standard document.
The IEEE does not warrant or represent the accuracy or content of the material contained herein, and expressly
disclaims any express or implied warranty, including any implied warranty of merchantability or fitness for a specific
purpose, or that the use of the material contained herein is free from patent infringement. IEEE Standards documents
are supplied “AS IS.”
The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase,
market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint
expressed at the time a standard is approved and issued is subject to change brought about through developments in the
state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least
every five years for revision or reaffirmation. When a document is more than five years old and has not been
reaffirmed, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present
state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard.
In publishing and making this document available, the IEEE is not suggesting or rendering professional or other
services for, or on behalf of, any person or entity. Nor is the IEEE undertaking to perform any duty owed by any other
person or entity to another. Any person utilizing this, and any other IEEE Standards document, should rely upon the
advice of a competent professional in determining the exercise of reasonable care in any given circumstances.
Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to
specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate
action to prepare appropriate responses. Since IEEE Standards represent a consensus of concerned interests, it is
important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason,
IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant
response to interpretation requests except in those cases where the matter has previously received formal consideration.
At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall
make it clear that his or her views should be considered the personal views of that individual rather than the formal
position, explanation, or interpretation of the IEEE.
Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliation
with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with
appropriate supporting comments. Comments on standards and requests for interpretations should be addressed to:
