Abstract

A method for indicating clock drift of an internal clock comprised in a sensor device, the method comprising: capturing S302, by the sensor device, first data frame; associating S304, by the sensor device, the first data frame with a first point in time indicating a point in time of the internal clock when the first data frame being captured; receiving S306, by the sensor device via a network protocol for clock synchronization, time synchronisation data; determining S308, by the sensor device using the time synchronisation data, a reference point in time indicating a point in time of a reference clock when the first data frame being captured; determining S310, by the sensor device, an offset between the first point in time and the reference point in time; and upon the offset exceeding a threshold offset, associating S312, by the sensor device, the first data frame with data indicating the offset.
