Zhongxin Chuangwei provides precise clock synchronization for the Petroleum University.

Recently, China University of Petroleum has launched a time server. of Demand , Beijing Zhongxin Chuang Company is actively cooperating For users A detailed plan has been prepared, and the independently developed and manufactured products of Zhongxin Chuang have been recommended. DNTS-8 Time Server As the product submitted for this tender, Zhongxin Chuang stood out by defeating competitors’ offerings thanks to its high‑quality products and comprehensive after‑sales service. End Awarded China University of Petroleum Time and Step server Project.

China University of Petroleum (East China) is Ministry of Education Directly affiliated National Key Universities , among the first batch at the national level Universities with World-Class Discipline Development , country “ Project 211 "and" Innovation Platform for Key Disciplines under the 985 Project “Key universities under development,” High-Level Industry-Specific University Quality Resource Sharing Alliance Member 。

China University of Petroleum Developed independently by Zhongxin Chuang DNTS-8 Time server Conduct an in-depth evaluation and arrive at the final results. All are superior to the parameter requirements. ， And Regarding our company’s product quality and after-sales service Also quite satisfied. ， Procured successfully and put into use. ！

Developed by Beijing Zhongxinchuang Technology Co., Ltd. The DNTS‑8 time server is a high‑tech, intelligent, stand‑alone clock synchronization server that operates on the NTP/SNTP protocols and delivers high‑precision time. It obtains standard time‑signal data from GPS satellites and disseminates this information across the network, enabling devices such as computers and controllers to synchronize with the reference clock. When all external signals are unavailable, the DNTS‑8 relies on its built‑in temperature‑compensated crystal oscillator for holdover, achieving a holdover accuracy of up to 1 × 10⁻⁹. The DNTS‑8 transmits standard time information over TCP/IP networks and supports multiple popular time‑distribution protocols, including NTP and time/UDP; it also accommodates custom‑defined time‑broadcast packets with configurable UDP ports. The port numbers for NTP and time/UDP are fixed at 123 and 37, respectively, as specified in RFC 123 and RFC 37. Additionally, the DNTS‑8 supports the broadcast mode of the SNTP protocol.
