Zhongxin Chuangwei provides clock synchronization equipment to Baidu.

Recently, Baidu issued a request for time servers. Beijing Zhongxin Chuang promptly collaborated to develop a detailed proposal and recommended its self‑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 Baidu’s time‑server project.

Baidu (Baidu) It is a leading AI company with a robust internet infrastructure. Baidu’s vision is to become a world-class high-tech enterprise that understands users best and helps them thrive. [1]

The two characters “Baidu” originate from a ci poet of the Southern Song dynasty, who lived eight hundred years ago. Xin Qiji A line from the poem goes: “I searched for him through countless crowds.” This phrase captures the poet’s unwavering pursuit of an ideal. At the end of 1999, while in Silicon Valley, Li Yanhong recognized the immense potential of China’s internet and Chinese-language search engine services. Driven by the dream of using technology to change the world, he resolutely resigned from his high‑paying job in Silicon Valley and, armed with his patented search engine technology, founded Baidu in Zhongguancun on January 1, 2000.

Baidu boasts tens of thousands of R&D engineers, forming a world‑class technical team that ranks among the best in China and globally. This team masters cutting‑edge search engine technology, positioning Baidu as a Chinese high‑tech enterprise that controls core technologies at the forefront of global science, and helping China become one of only four countries—alongside the United States, Russia, and South Korea—to possess proprietary search engine core technologies.

Baidu conducted an in-depth evaluation of the DNTS‑9 time server, independently developed by Zhongxin Chuang, and found that all performance metrics exceeded the specified requirements. Baidu also expressed strong satisfaction with our product quality and after-sales service, resulting in a smooth procurement and successful 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 in 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 rubidium atomic clock for timekeeping and continues to provide uninterrupted time services to external clients.

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‑9HG network time server are exceptionally straightforward: simply connect the satellite receiving antenna and link the network port to a network switch to achieve time synchronization for all devices on the network.
