STAC Independently Validates Hoptroff Timing Performance

Precision timing results across real-world network conditions

 Nanosecond precision

Measured at the business clock in local data center.

 Precision delivered across metro links

Mean offset of approximately 3.3µs across a 36 km production-style network path.

Stable performance under stress

99% of measurements remained within approximately 12.4µs across the remote link.

Why These Results Matter

These results demonstrate more than clock accuracy.


They show:

  • Nanosecond-level precision at source

  • Low single-digit microsecond accuracy across metro networks

  • Stable delivery across real-world network conditions

Timing performance engineered for real-world infrastructure.

What the STAC Study Assessed

The study measured how Hoptroff’s time synchronisation service performed against a GNSS-referenced clock across real-world network conditions.


It explored:

  • Timing accuracy

  • Resilient time delivery

  • Impact of switching infrastructure

  • Performance across metro distances


The result: strong evidence that resilient, traceable time can be delivered while maintaining high accuracy.
