Abstract: The invention relates to a method implemented in a V2X device (2) for exchanging V2X messages comprising data packets with one or more receiving V2X devices connected via a cellular communication network (4), the method comprising the steps of (a) running one or more V2X applications, running a V2X application comprising the generation of V2X message data associated with the V2X application, (b) transmitting the V2X message data to a distribution interface (203) at an injection time, and (c) transmitting the V2X message, in a format which is encoded using the message data retrieved from the distribution interface (203), to the receiving V2X devices via a radio link, using radio access technology, at a send time. The injection time is determined on the basis of an initial injection time defined by a predefined period. The method comprises a step of calculating the injection time of a current message on the basis of the initial injection time and time information relating to at least one previous V2X message sent by the V2X device via the radio link, the time information relating to a previous message comprising the injection time of the previous message into the distribution interface and the send time of the previous V2X message by the V2X communication device via the radio link.

Abstract: A method corrects the time defined by an internal clock of an entity capable of receiving signals from a satellite positioning system and of communicating with at least one other entity. When the signals do not allow the satellite positioning of the entity, the method includes: receiving, by the entity, a message originating from the other entity, the message including a first piece of time data associated with the instant the message was transmitted; determining, by the entity, a second piece of time data associated with the instant the message was received by the entity; calculating a time difference between the second piece of time data and the first piece of time data; and then, when the time difference is negative, determining a time correction to be made to the internal clock of the entity.
