The system compares estimates obtained from at least two heterogeneous and physically independent time or phase channels, referenced to a common reference configuration. It then determines a discrepancy measure Δ together with its corresponding uncertainty measure UΔ and creates a verifiable integrity record intended for independent verification based on the record itself.
The application covers a system, a method and an independent integrity-record verifier, as well as software and media containing that software, for certifying time and/or phase integrity.
The technology is intended for manufacturers, integrators and operators of timing, synchronization and PNT infrastructure that require independent, uncertainty-aware and subsequently verifiable evidence of time or phase integrity.
The system obtains time- or phase-related estimates from independent channels, brings them into a comparable form and determines Δ together with UΔ. The result is stored in an integrity record that can be checked by an external verifier.
The estimates originate from heterogeneous and physically independent channels.
The estimates are brought into a comparable reference configuration.
The discrepancy measure Δ and its corresponding uncertainty measure UΔ are determined.
The result and its verification context are stored in an integrity record.
The verifier checks the record and reproduces the specified result.
NTP, PTP and GNSS systems, local references and holdover mechanisms deliver, synchronize and maintain operational time. However, when time becomes the basis for an audit, dispute, failure analysis or cyber incident, a clock reading or synchronization alarm alone does not provide durable evidence of whether that time could be trusted within a specific window, what discrepancy occurred, what uncertainty accompanied the result and which data supported the assessment.
The technology converts a transient synchronization state into durable, measurable and independently verifiable evidence of time or phase integrity. It does not replace existing NTP, PTP or GNSS systems or synchronization infrastructure. Instead, it adds a certification layer that compares independent estimates, determines Δ together with UΔ and preserves the basis of the assessment in a record that can be checked later.
