Usage Advice

Use when

• Use to stamp the single instant a vouching act was issued — the wall-clock moment the attester signed and released the envelope.

Avoid when

• Avoid for the validity window (use gmeow:validFrom / gmeow:validUntil) or the verification time (that lives on the gmeow:VerificationResult); and because it is functional, a different issue time is a different attestation.

How to use

• Set one xsd:dateTime issue instant; bound usability separately with gmeow:validFrom/validUntil (revocation sets validUntil), and let transparency-log inclusion time ride on the gmeow:TransparencyLogEntry rather than here.

Examples

• ex:provAtt gmeow:issuedAt "2026-06-15T10:00:00Z"^^xsd:dateTime.
