Qualified timestamp (TSA)

Definition

A qualified timestamp is an electronic timestamp issued by a Trusted Stamp Authority (TSA) qualified under eIDAS. It produces legally recognized proof of a document''s existence at a specific date and time, linked to the document''s hash. Essential for PAdES B-T, B-LT, and B-LTA profiles to guarantee legal probative value over the long term.
