摘　　要：为满足军事系统对于时间同步的要求,设计并实现了一种基于综合化计算环境的时钟同步系统。通过接口板方式实现本地时钟代理,可对外部时钟源的时间信息进行解析和预处理,获取时钟基准,实现系统内其他功能模块的统一授时。性能评估结果分析表明该系统支持授时功能按需使用,具备良好的可扩展性和授时精度。For meeting the time synchronization requirements of military computer systems,an integration computing environment oriented time synchronization system is designed and implemented.To this end,the local clock agency module is deployed in the form of interface board,which can acquire system clock reference and achieve timing calibration of other functional modules based on the pretreatment to the timing information from external clock sources.Performance evaluation shows that the system can support the on-demand timing services,and be equipped with well scalability and precision.
