A method at a first device for synchronising a first clock of the first device to a second clock of a second device, includes receiving a first message comprising an identifier from a third device; generating a first timestamp in dependence on the time at which the first message is received at the first device according to the first clock; receiving a second message from the second device comprising the identifier and a second timestamp, the second timestamp having been generated in dependence on the time at which the second device received the first message from the third device according to the second clock; and adjusting the first clock in dependence on a time difference between a time indicated by the first timestamp and a time indicated by the second timestamp.
