Clock Quorum: precision with proof

...another riveting video from the Timebeat back office... 😂

I'm proud to show you one of the smallest, most powerful Grandmaster Clocks (GMCs) on the market: the Open Time Appliance. With three units fitting neatly into just 1RU of rack space, and the capability to house atomic oscillators, this solution truly redefines performance and density.

... but what good is precision without proof?

At the heart of our philosophy is a simple truth: sync without consensus is guesswork. That’s why we’ve engineered our Clock Quorum Technology to provide exactly what modern networks need — a consensus-driven, verifiable source of time.

It’s not just about using the latest from u-blox or integrating atomic precision — it’s about verification. Verify that your time is right. That your systems are in sync. And that your data stands on solid ground.

We’ll be hitting the road with the Open Time Appliance at STAC in London, New York, and Chicago — bringing real-time demos and deep dives into how we’re redefining confidence in time through consensus.

Because in a world where nanoseconds matter — precision isn’t enough. Proof is everything.

Clock Quorum Technology
The power of 3, because precision needs proof.
The Open Time Appliance, has built in clock quorum technology, not only for resilience but to evidence the synchronisation capabilities.
Too many devices on the market claim precision with little in the way of testing capabilities, our systems provide raw evidence with clear metrics and comparisons through a concenses mesh.


Low on Space & Power
With all 3 units only taking up 1RU of 19" rack space. You no longer need to sacrifice expensive datacentre space and power resources for gold standard timing.All of our units fit the same form factor, which means even a rubidium device is capable of being deployed in even the most space constrained environments.


Resilience and Redundancy
Tripple modular redundancy provides the most robust and resilient system. This is not only fault tolerant but also enhnaces synchronisation capabiities. The Open time appliance is a low cost solution to tripple modular redundancy as purchasing 3 units is typically less than 2 units from our competitors.


<5ns Accuracy and Precision
Flagship solutions integreated into all of our models from Ublox allow these devices to be accurate to less than 5 nanoseconds to UTC.
With advanced features for anti-jam and anti-spoof counter measures these units maintain accuracy and precision even during sub-optimal conditions

Precision with proof

Three clocks. One rack unit. No guesswork.

Clock Quorum turns independent grandmasters into a self-verifying source of time.
