Zhongxin Chuangwei provides a precision clock to Zhenhu Experimental Primary School in the Jiangsu High-Tech Zone.

Zhongxin Chuangwei provides a precision clock to Zhenhu Experimental Primary School in Jiangsu High-Tech Zone.

Recently, Zhenhu Experimental Primary School in Jiangsu High-tech Zone issued a request for a time server. Beijing Zhongxin Chuang promptly collaborated to develop a detailed proposal and recommended its self‑developed and manufactured DNTS‑6 model 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 time‑synchronization project for Zhenhu Experimental Primary School in Jiangsu High-tech Zone.

Zhenhu Experimental Primary School is located at Taihu Lake On the shores of…, the “Hometown of Chinese Embroidery Art”— Suzhou Zhenhu in the High-tech Zone. Established in 1914, it boasts nearly a century of history. The school occupies an area of 20,637 square meters, including its buildings. Area Covering 7,240 square meters, the school enrolls nearly 1,000 students and employs close to 100 faculty and staff members, including three senior‑level secondary school teachers, 53 senior‑level primary school teachers, three with master’s degrees, 46 with bachelor’s degrees, and 25 with associate degrees. The campus is equipped with a 200‑meter synthetic track, various sports fields, a roller‑skating training facility, and other comprehensive athletic amenities. It also boasts a range of specialized classrooms, such as a dance studio, a Suzhou embroidery workshop, a Pingtan classroom, a science and technology innovation lab, an aviation‑modeling training base, and a roller‑skating instruction center. As urban–rural integration deepens, the school is committed to fostering substantive development, highlighting its distinctive strengths, and striving to become a high‑standard, modern institution that stands out for its unique character, superior quality, pleasant environment, and widespread public satisfaction.

Zhenhu Experimental Primary School in the Jiangsu High-Tech Zone conducted an in-depth evaluation of the DNTS‑6 time server independently developed by Zhongxin Chuang. The results exceeded the specified performance parameters, and the school expressed high satisfaction with both our product quality and after-sales service, proceeding to place a successful order and put the system into operation.

The network time server DNTS-6, developed by Beijing Zhongxinchuang Technology Co., Ltd., is a high-tech, intelligent, stand-alone time server based on the NTP/SNTP protocols. DNTS-6 obtains standard clock signal information from GPS geostationary satellites and transmits this information over the network, enabling devices that require time signals—such as computers and controllers—to synchronize with the standard clock. Standard clock information is transmitted via the TCP/IP network, and DNTS-6 supports multiple popular time‑broadcasting protocols, including NTP and time/UDP, as well as Zhongxinchuang’s proprietary time‑broadcast data 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, DNTS-6 supports the broadcast mode of the SNTP protocol.
