Introduction to Clock Sync in Finance and Beyond

Posted by Victor Yodaiken on Nov 01, 2017
Categories: Financial Sector

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).

MiFID II - Ten Things You Need to Know About Clock Sync

Posted by Victor Yodaiken on Jan 06, 2017
Categories: Clock Sync, ESMA, MiFID2, MiFIDII, Whitepaper

Not only does MiFID II explicitly require working clock synchronization, but many of the recordkeeping requirements also cannot be met if time is not verifiably synchronized during the entire trading day. Here’s what you need to know:

Cloudflare Leapsecond Lurch and time sync engineering

Posted by Victor Yodaiken on Jan 02, 2017
Categories:

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.

Minimizing Spend on MiFID II Compliance

A customer recently pointed me at a series of blog posts about a project at a financial firm trying to comply with MiFID II clock regulations without TimeKeeper and “with minimum spend”. Reading the posts, it’s clear that costs are already well over what it would have cost them to buy TimeKeeper and they have a lot of work left.

The system he had built was remarkable in its complexity and fragility. Nobody seemed to understand how it worked. Accuracy was highly variable. There was no management, no documentation. We never got to meet the Professor, but I always thought of him as something like this.

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”.

We’ve seen some ‘interesting’ problems in deployed timing infrastructures. PTP Grandmasters that stop providing time on the network.
