The CEN 13149 series of products concerns on-board data communication systems on public transport vehicles. This series provides for data services that enable open and managed sharing of relevant information.

This document, being Part 9 of the series, specifies a time publication, enabling all on-vehicle services to share a common understanding of current time, based on a suitable agreed master network clock. It covers:

• the functional scope, i.e. which data the service provides, why, when and how often.

• the transport protocol, i.e. how the data are transmitted.

• the service publication, i.e. how the service can be found by other modules or applications

• the structure of the data, i.e. how the data are structured and how the data elements are named.

This document implements the service framework described in CEN/TS 13149?7.
