Apple Watch time technology

Posted by Victor Yodaiken on Sep 18, 2019
Categories: TimeKeeper, Timemap

Apple says its new consumer electronic watch will synchronize to within 50 milliseconds of UTC time. Most of our customers in the financial trading sector need time to be within a microsecond - 50 thousand times better, but we were interested in what Apple is doing so we pointed TimeKeeper® at time.apple.com and looked at the time map -which is reproduced above.

Best Practices with TimeKeeper® SourceCheck (2016)

Posted by Victor Yodaiken on Aug 28, 2019
Categories:

The TimeKeeper ‘SourceCheck’ feature is an analytics and automated threat detection tool that allows TimeKeeper to detect bad time sources and switch away from them. Bad time can come from misconfiguration, equipment and software failures or intentional time based attacks. SourceCheck can detect and defeat them.

TimeKeeper Versus Solarflare SFPTPd Comparison

Posted by victor yodaiken on Aug 23, 2019
Categories: Whitepaper

TimeKeeper time and clock synchronization sets the standard for Enterprise and for Financial Trading. TimeKeeper management, fault-tolerance, traceable audit, and superior accuracy are not matched by any other product. This technical note compares TimeKeeper’s operation in the presence of a common network issue with the operation of free software provided to purchasers of Solarflare's PTP enabled network cards.

Introduction to Clock Sync in Finance and Beyond

TimeKeeper Client software runs on an application server computer (Linux, Windows, Solaris) and locks the system clock to time from some authoritative source (like a GPS clock). On standard enterprise networks, TK Client can make the system clock accurate to well below one microsecond. TK Client can receive time over either or both of the common network protocols for time distribution (PTP IEEE 1588 and NTP).

Time Synchronization for AWS and RHEL with TimeKeeper®: a solved problem

Posted by Victor Yodaiken on Mar 01, 2017
Categories: Clock Sync, Linux, Whitepaper

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 virtualized environment where system time does not always match “real time”. Getting past that is pretty easy now, though. Below we show that using the TimeKeeper software on an AWS system using a RHEL AMI demonstrates very clearly that with the proper setup those time accuracy milestones are easy to achieve.

Cloudflare Leapsecond Lurch and time sync engineering

Posted by Victor Yodaiken on Jan 02, 2017
Categories: Leap Second

The default behavior of many clock synchronization systems is to lurch the clock on a leap-second but for TimeKeeper, default behavior is few minutes of speeding up or slowing down the clock (slewing) in order to prevent failures. Lurching or “stepping” on most leap seconds involves repeating a second on the clock.

How financial trading firms can get the time wrong by 35 seconds

Posted by Victor Yodaiken on Apr 22, 2014
Categories:

There is a regulation called FINRA rule 7340 which requires US financial traders to keep their clocks synchronized to within one second of the official time from the National Institute of Standards and Technology (NIST). This standard is probably way too weak for modern trading, which often takes place in microseconds, but even so, complying with the standard is a lot harder than it appears. In fact, clocks that are wrong by 35 seconds are not all that unusual because of astronomy and “leap seconds”.

TimeKeeper® CloudTiming™ Architectures: Cloud, AWS EC2 & Virtual Host Time Sync

Posted by Victor Yodaiken on May 19, 2013
Categories: Cloud, Whitepaper

TimeKeeper time synchronization client, server and management software efficiently handles the unique environment of the cloud and virtual hosts. Legacy time synchronization solutions fail to synchronize time properly on virtual systems because they cannot cope with an environment where the clock is virtualized and may show discontinuous gaps in time. As a result, applications depending on legacy time synchronization technology in the cloud see time jump, lurches, and divergences. TimeKeeper recognizes this environment and is designed to synchronize the clock properly - always. With proper configuration, it’s possible to have near bare-metal hardware accurate time.
