Timestamping Authority is an on-premises timestamping solution based on RFC 3161 that guarantees that data, including documents or code, exists at a given time through the generation of digitally signed timestamps. Specifically:

• Proof of the time when a digital signature was applied or validated.
• Prevents code rejection, ensuring that the signature is valid when signing.
• Enables digital signature verification after the certificate used for the signature is revoked or expired.
