Time Stamp Authority

Time Stamp Authorities (TSA) issue digitally signed timestamps (RFC 3161) that are optionally used during signed PDF export.

Adding a trusted timestamp to an electronic signature provides a digital seal of data integrity and a trusted date and time of when the transaction took place. Recipients of documents with a trusted timestamp can verify when the document was digitally or electronically signed, as well as verify that the document was not altered after the date the timestamp vouches for.
