The network time service is a kind of  time and frequency transfer method making use of network. It is mainly used to calibrate the local time of client in network. A network time service system (NTSS) is constructed and maintained at NIM. The 1PPS and 10MHz signals from UTC (NIM) serve as reference sources of the NTSS, UTC (NIM) serves as standard time of the NTSS, and the NTSS is connected into Internet by the IP address to provide the time service (Fig. 1). The clients can get the accurate time synchronizing information with high speed from NTSS of NIM for free. The precision of time synchronization is usually less than 100ms under unblocked Internet condition.
