RFC 3161 timestamp
A cryptographic timestamp from a trusted authority proving a document existed at a given time and was not backdated.
RFC 3161 defines a trusted timestamp: a Time-Stamping Authority signs a hash of your document, proving it existed at that moment and has not been altered or backdated. It is the load-bearing element of tamper-evident evidence.
WCAGdesk timestamps each scan record this way, so a dated proof of your accessibility findings can be verified independently — see the evidence specification.
