Precision Time Exchange
Quincy Data delivers resilient, sub-nanosecond time synchronization across major North American trading venues, fully traceable to UTC(NIST)*.
It offers a robust alternative to locally maintained GPS clocks, helping market participants address rising risks of interference and degradation in time signal reliability.
"Timestamping that is reliable, picosecond-precise, and accurately available across multiple venues is an exceptionally hard technical challenge. Precision Time Exchange solves it. It is a uniquely resilient service that can replace the in-house time transfer systems financial firms are currently forced to build, maintain, and improve themselves."
The Challenge
As uncertainty grows around the reliability of localized GPS infrastructure, time-sensitive institutions—including exchanges, ATSs, market makers, and data providers—are increasingly seeking dependable external time sources.
Precision Time Exchange was engineered to support every major U.S. trading campus, enabling firms to avoid the burden of developing and managing their own precision timing systems.

Why Firms Rely on Quincy Data for Time
Why Precision Time Exchange?
Yes — we call it an exchange because that's exactly what it is.
Our Precision Time Exchange facilitates what experts call time transfer: the process of accurately sharing time information between our precisely calibrated infrastructure, traceable upstream to UTC(NIST)*, and your systems.
This is not just a one-way broadcast — it's a continuous, dynamic exchange of information.
We account for offsets, track changes in ionospheric propagation, and compensate for differences in GPS satellite signals over time. By exchanging this critical information, we ensure your infrastructure stays tightly synchronized to UTC-traceable time.
Service Delivery
We deliver this service through multiple protocols and configurations to match your architecture:
PTP Feeds
Precision Time Protocol feeds for standard network synchronization
White Rabbit
White Rabbit-compatible feeds for ultra-precise synchronization
Dual A & B Feeds
Resilient feeds for robust, independent synchronization paths
Every delivery is designed to provide precision, traceability, and reliability, no matter your architecture.
