Timestamp

A timestamp is a cryptographically verified record of the exact time a document or signature was created, issued by a trusted third party.

Full Definition

Unlike a device's system clock, which can be falsified, a qualified timestamp is issued by an accredited service and is bound to the document content via a hash function. Timestamps are essential for long-term archival of digital signatures, as they allow the validity of a signature to be proven even after the signer's certificate has expired.
