Abstract

See full text

A method includes sending, from the master controller to the slave controller, a follow up message in response to a pull of a predefined pin, wherein the follow up message includes a global time of the master controller when the predefined pin was pulled; sending, from the slave controller to the master controller, a validation message in response to the received follow up message, wherein the validation message includes a global time of the slave controller when the pull of the predefined pin is detected by the slave controller; and validating the time synchronization by checking, at the master controller and/or the slave controller, if a difference between the global time of the master controller when the predefined pin was pulled and the global time of the slave controller when the pull of the predefined pin is detected by the slave controller is smaller than a predefined first threshold.
