Core Capabilities

Built for systems where time integrity is non-negotiable.

Signed Timestamps

Every timestamp is cryptographically signed and independently verifiable.

Monotonic Ordering

Guarantees strict event ordering across regions and failure boundaries.

Audit Trails

Immutable time logs designed for compliance, forensics, and dispute resolution.

Time Synchronization

Hybrid NTP-plus-cryptographic synchronization with adaptive drift correction.

GET /v1/time/sync Authorization: Bearer <token> { "server_time": "2025-12-26T15:41:09.381Z", "offset_ms": -1.7, "signature": "c9f8e3a4b12d..." }

Example Endpoint

Verifiable timestamp issuance for mission-critical events.

POST /v1/timestamp/issue Authorization: Bearer <token> { "event_id": "txn-884291", "hash": "5e884898da28047151d0e56f8dc62927", "issued_at": "2025-12-26T15:42:11Z" }

Roadmap

Advancing trust in time-sensitive systems.
