Network security trends continue to evolve.  The National Institute of Standards and Technology (NIST) has defined the Zero Trust Architecture (ZTA) which refers to the narrowing of network defense perimeters.  EndRun has a long history of engineering trustworthy and secure network equipment that is inline with this NIST publication. 

This paper will show that the NTP and PTP timestamps from EndRun Technologies Network Time Servers are traceable through the National Institute of Standards and Technologies (NIST), and the United States Naval Observatory (USNO) to Coordinated Universal Time (UTC) maintained by the International Bureau of Weights and Measures (BIPM). 

Today, High Frequency Trading (HFT) requires low latency and knowledge of UTC time in capital markets where a difference of better than one millisecond provides a competitive advantage to trading firms.  Better than 10-microsecond accuracy to UTC can be achieved using Code Division Multiple Access (CDMA) and IEEE-1588 Precision Time Protocol (PTP) without routing an external antenna. Presented at the 42nd Annual Precise Time and Time Interval Systems and Applications (PTTI) in November 2010.

The Precision Time Protocol, as defined in the IEEE-1588 standard, provides a method to precisely synchronize computers over a Local Area Network (LAN). PTP is capable of synchronizing multiple clocks to better than 100 nanoseconds on a network specifically designed for IEEE-1588.
