Time and frequency


A resilient, traceable and certified time distribution service for the financial sector that completely eliminates reliance on GPS.

Achieve certified compliance with NPLTime® and eliminate the weaknesses of GPS

Since 3 January 2018, financial reporting systems must legally comply with stringent new EU regulations for time-stamping on financial trades – known as 'MiFID II RTS 25'.

That's why the UK's official UTC timekeeper, the National Physical Laboratory (NPL), has created NPLTime®. This end-to-end 'time-over-fibre' service is delivered to the financial sector in partnership with leading network infrastructure providers (please note that some geographical restrictions apply).

NPLTime® delivers all four core elements of your ideal MiFID II-compliant timekeeping solution that eliminates the weaknesses of GPS. There are two service types available – choose from Enterprise or Colo to meet your business needs.

NPLTime® delivers four core elements


A direct fibre link to the UK's timescale UTC(NPL) eliminates the uncertainties of GPS signal paths.


Designed for complete reliability and redundancy, while the secure and robust fibre connection protects you against the signal interference or malicious spoofing vulnerabilities of GPS.


Your UTC accuracy is certified at the point of usage within your own datacentre by NPL, the UK's National Measurement Institute and only UK UTC timekeeper. No GPS solution can offer similar reassurance.


NPLTime® is an intelligent and cost-effective 'UTC as a Service' solution, integrating end-to-end infrastructure, technology and management for swift and practical implementation.

Delivering trusted time for UBS infrastructure via NPLTime®


Our white papers

NPLTime® disseminated through the UBS infrastructure

A trial of the NPLTime® commercial service was conducted at the UBS facility in LD4 Slough, where the signal was consumed and assessed within the UBS infrastructure to validate the source, internal distribution architecture and systems, and timestamping solutions. This white paper outlines the implementation and results of the trial from the NPLTime® Distribution hub located at Telehouse, Docklands, and delivered to Slough on TMX Atrium connectivity.

Time Traceability for the finance sector

This document aims to describe the key concepts that underpin the emerging requirements for accurate time-stamping of transactions in the financial sector. The topics covered include: the international time system and the importance of UTC; the concept of traceability for time measurements; and the terminology used for traceability in time dissemination and time stamping.

NPLTime® – certified time for the financial sector

In the run-up to MiFID II implementation, NPL and ICE carried out a proof-of-concept to assess the NPLTime® service for its suitability for the impending regulations.
