  This paper presents a new time transfer system that works with any radio
signal with sufficient bandwidth, regardless of its content and modulation, by
adopting the common view approach. This system, based on a network
client-server architecture with SDR receivers offers a number of advantages. It
can compare remote atomic clocks or disseminate reference time scales to end
users with precision at the level of tens of nanoseconds. Its improved features
in terms of flexibility, robustness, reliability, and security will potentially
make positive contributions in the field of time transfer, as an alternative or
complement to existing methods.
