摘　　要：介绍了国际原子时(TAI)、协调世界时(UTC)以及我国标准时间UTC(NTSC)的产生和发展。简要介绍了国际标准时间的定义、国际时间比对技术的发展、TAI和UTC计算方法、工作规范的发展和未来可能的形态。介绍了我国原子时工作的历史和发展,以及时间基准保持性能、国际比对及溯源和时间信号服务方面的最新进展。The generation and development of International atomic time scale（TAI） and the independent local atomic time scale TA（NTSC） are presented in this paper. The algorithm, work specifications and definition of TAI, as well as the progress and development of international time comparison techniques are introduced briefly. The progress and development of modern time service work in China are introduced, including timekeeping performance realized, international time link, traceability and time signal services.
