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.

Hoptroff’s developer surface includes engineering blog, support, and 6 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/hoptroff: open an issue to ask a question, or submit a pull request to add artifacts.

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
