Zhongxin Chuangwei provides clock synchronization equipment to Guiyang Rural Commercial Bank.

Recently, Guiyang Rural Commercial Bank issued a request for a time server. Beijing Zhongxin Chuang promptly collaborated to develop a detailed proposal and recommended its independently developed and manufactured DNTS‑9 time server as the bid‑winning product. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, ultimately securing the contract for the Guiyang Rural Commercial Bank’s time‑server project.

Guiyang Rural Commercial Bank Co., Ltd., abbreviated as “Guiyang Rural Commercial Bank,” is a locally state‑owned bank under the direct leadership of the Guiyang Municipal Party Committee and Municipal Government, and it is the largest regional rural corporate financial institution in the province. Established through the comprehensive restructuring of the former rural credit cooperatives (combined banks) from the four urban districts of Yunyan, Nanming, Xiahe, and Baiyun, Guiyang Rural Commercial Bank became the province’s first joint‑stock rural commercial bank. It was officially listed on December 23, 2011, with a registered capital of RMB 2.39 billion.

On September 6, 2019, the Guizhou Enterprise Federation and the Guizhou Entrepreneurs Association jointly released the 2019 Top 100 Enterprises in Guizhou, with Guiyang Rural Commercial Bank Co., Ltd. ranking 45th.

Guiyang Rural Commercial Bank conducted an in-depth evaluation of the DNTS‑9 time server independently developed by Zhongxin Chuang. The results consistently exceeded the specified performance parameters, and the bank expressed strong satisfaction with both our product quality and after-sales service, leading to a successful procurement and deployment.

The DNTS-9 network time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is an intelligent, high-precision NTP network time server. The DNTS-9 obtains standard time information from the GPS navigation and positioning satellite system and provides standard time services over the network via NTP/SNTP or other network protocols. Devices on the network that require time synchronization—such as personal computers, servers, and controllers—can synchronize with international standard time. When using a GNSS satellite receiver, users can define priority levels and configure single-receiver/dual-receiver or single-antenna/dual-antenna setups; each receiver can be set to operate in standalone or combined timing modes. If both receivers and other available time sources lose signal, the DNTS-9 relies on its built-in temperature-compensated crystal oscillator for timekeeping and continues to provide uninterrupted time services to external devices.

In addition to serving as a primary‑level network time‑synchronization device, the DNTS‑9 can also function as a secondary‑level time server, enabling more effective time synchronization in large‑scale network environments. It provides precise standard time signals for systems such as distributed networks, computer security systems, file management systems, e‑commerce platforms, online B2B systems, and cloud database storage and maintenance. The DNTS‑9 has been successfully deployed across government, finance, mobile telecommunications, public security, petroleum, power, transportation, industrial, and defense sectors. Installation and operation of the DNTS‑9 network time server are exceptionally straightforward: simply connect the satellite receiving antenna and link the Ethernet port to a network switch to achieve time synchronization for all devices on the network.
