The National Institute of Standards and Technology (NIST), through a collaboration with Perseus, a global provider of telecommunication services, is providing accurate, traceable, and verifiable time synchronization to stock exchanges in the United States, Europe, and Asia. The paper describes why accurate time is necessary for fair and equitable financial markets and summarizes current and proposed future synchronization requirements in the financial sector. We discuss reference time sources and provide a technical overview of how NIST transfers time to data center hosted stock exchange. We also discuss how Perseus distributes NIST time to financial market customers and describes how the time is verified. Measurement data are presented, along with a discussion of measurement uncertainty.
美国国家标准与技术研究院（NIST）与全球电信服务提供商珀尔修斯公司合作，正在为美国、欧洲和亚洲的证券交易所提供准确、可追溯且可验证的时间同步服务。本文阐述了准确时间对于公平公正的金融市场为何必不可少，并总结了金融领域当前及未来拟议的同步要求。我们讨论了参考时间源，并对NIST如何将时间传输到托管在数据中心的证券交易所进行了技术概述。我们还讨论了珀尔修斯公司如何将NIST时间分发给金融市场客户，并描述了时间是如何得到验证的。文中给出了测量数据，并对测量不确定度进行了讨论。
