A system and method for providing secure, end-to-end data service enabling real-time data over the Internet is disclosed. The first terminal device receives a GPS-data from a GPS satellite, executes a first correction procedure on a satellite time-data of the GPS data to generate a first time-data, and transmits the first time-data to the communications relay device. An output section is connected to the self terminating pre-charge section and produces an output clock at an output section output.
