Aiming at the requirements of network user in many fields for high precision time synchronization in networking, the principles of timing and time uniform, B code, NTP and PTP are introduced. A timing and time uniform system is designed and implemented, and the timing precision experiments are implemented with the professional test apparatuses. The experiment results show that the timing and time uniform system has the timing accuracy from milliseconds to nanoseconds, can provide high-precision timing services to network users such as B code, NTP and PTP, and especially provides a feasible means for realizing remote networking time synchronization for the long-distance distributed users.
