Abstract
Network time service system is constructed in NIM based on network time protocol (NTP). The synchronization software program based on NTP is run at the client side. The mathematical uncertainty model of time offset is established. The uncertainty is analyzed and evaluated. The uncertainty of time server and client are evaluated particularly by the synchronizing experiments using a time and frequency solutions TimeAcc-007. The data processing algorithms are proposed for improving synchronization precision based on the result of uncertainty evaluation.
