Claim:
1. A system comprising at least a timing slave device and a timing master device, wherein each timing slave device includes or has access to a time reference, wherein the timing master comprises or has access to a master time reference, wherein said timing master device and said timing slave device are operatively arranged for transmitting and receiving radio signals, characterized in that the timing master is operatively arranged for transmitting time signals to said slave device said time signals comprising a plurality of frequency chirps encoding an absolute time information derived from the time reference of the timing master, for time-stamping the time signals received from the timing master by the timing slave device and for synchronizing its time reference with the time reference of the timing master based on the time stamps, on a propagation time to the timing master, and on said frequency chirps.
