Clock synchronization and Technology The developers of Google’s Spanner database built an interesting system but chose to build their own clock synchronization technology instead of getting a more precise off the shelf solution and chose to make extensive use of the notoriously complex Paxos distributed consensus algorithm even though they were incorporating clock sync into their system.…
Clock Synchronization in Finance and Beyond Introduction FSMLabs produces a suite of clock synchronization products under the name TimeKeeper®, primarily for customers in financial trading but also for a wide range of customers in other fields: from first responders to internet gaming providers, managers of big data systems, and radio/TV recording and broadcast. Clock synchronization…
TimeKeeper® routinely produces sub-microsecond accuracy from NTP sources. In the graph below, a TimeKeeper client tracks an NTP source to within 140 nanoseconds. The client is setup with four sources: two independent GPS sources for validation (blue and green), a PTP source (yellow), and an NTP source (orange). The worst case (not average) NTP source accuracy is within…

Clock Accuracy and Traceability How Do We Know When Clocks are Synchronized? Clock synchronization software on an application server computer usually relies on time delivered over the network and so does not have enough information to know when it has accurate time. The best this software can do is estimate how well the system clock…
Introduction to Clock Sync in Finance and Beyond Clock sync is still a mysterious topic to many, so here is an introduction to our business. Clock sync is still a mysterious topic to many, so here is an introduction to our business. Read whitepaper Product. FSMLabs sells a mostly software product called TimeKeeper mostly to…
A 2014 paper by engineers at IMC, NYSE, and Deutsche-Boerse spotlights single point of failures in IEEE 1588 PTP. Read More >
View the TimeKeeper Grandmaster, Compliance and Active Client deployment architecture which highlights that TimeKeeper clients get time via PTP or NTP from TimeKeeper grandmasters. In addition, TimeKeeper Compliance runs on your own hardware to collect client logs and generate reports and gets data from grandmasters. Also, Compliance instances communicate to share data between data centers…
Accurate time synchronization in AWS is easy to achieve for those who want it. New financial regulations (MiFID II and FINRA changes) require 1 millisecond and sometimes 100 microsecond accuracy to UTC time. Many social media, gaming and other applications require similar accurate timing. In the past that was not easy since AWS is a…
