Hoptroff

Hoptroff is a London-based precision timing company that delivers Traceable Time as a Service (TTaaS), providing enterprise-grade, traceable UTC time with guaranteed SLA accuracy to any data center or cloud environment. Founded in 2015 by Richard Hoptroff, the company operates a global network of atomic timing hubs in London, New York, and Tokyo, delivering microsecond-level precision over IEEE 1588 Precision Time Protocol (PTP) and NTP. Its Certified Time and Terrestrial Time Feed products let organizations timestamp and audit automated events without a satellite dependency, using resilient multi-source feeds (three satellite feeds plus a terrestrial feed from the RISE Institute of Sweden) that are hardened against GPS spoofing and network failure. Hoptroff is certified to ISO 27001 and ISO 9001, and its time synchronization is licensed as an API so a consistent, compliant timescale can be applied across an enterprise for use cases in financial services (MiFID II timestamping and high-frequency trading), content streaming, gaming, IoT, and distributed ledger technology.

Hoptroff is profiled on the APIs.io network. Tagged areas include Company, Precision Timing, Time Synchronization, Time as a Service, and PTP.
