What is it?
Accurate time sync with dynamic 25-sigma clock bounds for any environment
- 3 orders of magnitude more accurate than typical NTP
- Each timestamp is expressed as an interval (earliest, latest), with sub-millisecond bounds
- Support both software and hardware timestamps
- Run in any environment, from public cloud to on-prem
- Intuitive dashboards for monitoring and visualizing clock performance
API Definition
We support the following calls
- now()
Returns an interval (earliest, latest) that encloses the current time - after (t)
Returns true if the current time is guaranteed to be after t; returns false otherwise - before (t)
Returns true if the current time is guaranteed to be before t; returns false otherwise
Performance
Converge clocks in seconds, not hours, and see a 10-100x improvement in distributed database applications.
- 25-sigma bounds with software timestamps = stays within ~500μs
- 25-sigma bounds with hardware timestamps = stays within ~50μs
- Reduce retry probability by an order of magnitude
