Open, scalable and validated reference architecture

Introducing the future of Open Time Servers:

  • Scalable design for seamless time distribution

  • External source, like GNSS signal

  • Aligned with DC accuracy and stability

  • Embracing open-source software

Open Time Server

The Open Time Server (OTS) is a project within OCP-TAP to democratise timing solutions and the G0kK-1 Series is the most powerful deployment to date.

What is it?

The Time Card and Timebeats expertise allows any x86 machine with a NIC capable of hardware time-stamping to be turned into a best-in-class Grandmaster time system.

x86 Servers Transformed in No Time

This system is agnostic to whether it runs for NTP, PTP, SyncE or any other time synchronisation protocol since the accuracy and stability provided by Time Card is sufficient for almost any system.

Open Source

Rich In Features

The Time Card operates with open sync stacks as well as pairing perfectly with Timebeat’s Enterprise sync software

Traditional grand master clocks have limitations:

  • Hardware appliances, not ideal for data centers (DCs)

  • Non-standard interfaces and software

  • Lengthy, expensive development cycles

  • Lacking open-source software

  • Inaccurate for DC requirements
