Core Viewpoint - The article discusses a significant cyber attack by the U.S. National Security Agency (NSA) on China's National Time Service Center, aiming to undermine China's time sovereignty and disrupt critical infrastructure [1][2]. Group 1: Cyber Attack Details - The NSA has been planning the cyber attack on the National Time Service Center for an extended period, employing a systematic approach with new cyber warfare platforms and 42 specialized attack tools from August 2023 to June 2024 [1]. - The attacks are characterized by high intensity and attempts to penetrate various internal network systems, with the goal of incapacitating China's high-precision timekeeping systems [1]. - The NSA's operations typically occur during late night to early morning Beijing time, utilizing virtual private servers from multiple global locations to obscure the source of the attacks [1]. Group 2: Importance of National Time Service Center - The National Time Service Center, located in Xi'an, Shaanxi, is responsible for broadcasting "Beijing Time," which is crucial for various sectors including communication, power, transportation, and defense [3][8]. - The center has developed high-performance atomic clocks, achieving a time accuracy of 600 million years without deviation, positioning China at the forefront of global timekeeping precision starting in 2024 [9]. Group 3: Implications of Time Disruption - Disruption of "Beijing Time" could lead to severe consequences, such as power outages, significant fluctuations in international stock markets, and inaccuracies in navigation systems like BeiDou [9]. - The NSA's intent to disrupt the time standard is seen as a strategy to hinder China's technological and economic development by targeting critical infrastructure [9]. Group 4: BeiDou System and Time Sovereignty - The BeiDou satellite navigation system not only provides positioning and navigation but also plays a vital role in timekeeping, enhancing China's control over precise time distribution [11][13]. - BeiDou's time synchronization capabilities, with an accuracy of up to 10 nanoseconds, allow users to correct local time discrepancies, further solidifying China's time sovereignty [12].

Core Viewpoint - The article discusses the importance of accurate timekeeping in modern society, highlighting that the official time in China originates from the National Time Service Center in Xi'an, Shaanxi Province, and emphasizes the implications of time accuracy for various sectors, including finance and national security [8][10][44]. Group 1: Timekeeping and Its Importance - The unified and precise Beijing time is crucial for the functioning of society, as it serves as the foundation for various systems [8][10]. - The National Time Service Center has been under cyberattacks from the United States for nearly two years, indicating the strategic importance of time management [9][10]. - Accurate time is essential for high-precision fields such as aerospace, satellite navigation, and financial transactions, where even a slight error can lead to significant consequences [18][38]. Group 2: Mechanisms of Timekeeping - The National Time Service Center employs two main methods for time dissemination: ground-based and space-based systems [26][27]. - Ground-based time dissemination includes shortwave radio broadcasts and low-frequency time code signals, achieving millisecond to microsecond accuracy across the country [28][30][39]. - Space-based time dissemination relies on Global Navigation Satellite Systems (GNSS), such as GPS and BeiDou, which provide time signals with nanosecond precision [34][36]. Group 3: Implications for Various Sectors - In finance, accurate time signals are critical for transactions, as they follow a "price priority, time priority" principle, where the speed of order execution can determine success or failure [39][40]. - Regulatory bodies in the EU and the US require financial institutions to synchronize their systems with standard time, emphasizing the need for precision in timekeeping [43]. - The military also relies on precise time coordination for operations, where discrepancies can lead to confusion and loss of control [43][44].
