From the National Physical Laboratory: the UK’s official UTC timekeeper

NPLTime® offers the financial sector a certified precise time signal, directly traceable to Coordinated Universal Time (UTC) and independent of GNSS. Since 3 January 2018, financial reporting systems must legally comply with stringent EU regulations for time stamping on financial trades known as MiFID II RTS 25.

That’s why, as the UK’s official UTC timekeeper, we have created NPLTime®. This end-to-end, ‘time-over-fibre’ service is delivered to the financial sector, in partnership with leading network infrastructure providers.
