Workflow

TEE-attested clock.

Long-running multi-party workflows need timestamps no single participant can lie about. The AttestedTimestamp envelope wraps wall_ms + monotonic_ns + vendor + enclave_id + attestation_hash + signature so DvP deadlines, AP2 mandate expiries, margin-call grace periods, and parametric-insurance trigger windows anchor to a hardware-attested clock.

When to use

Workflow step deadlines, AP2 mandate expiry, parametric-insurance trigger windows, margin-call grace periods, DvP settlement windows. Don’t use it for in-memory ephemeral state or the pure consensus path (block timestamps are already attested by the QC).

Verification

Relying parties check three invariants: drift tolerance (default 30s per Canton 3.5 guidance), monotonic counter (strictly increases per enclave id — detects rollback), and the signature over the canonical preimage.
