A list of timestamping authorities (TSAs) seen "in the wild" as used for QES document signing in Lithuania.
This page serves little practical purpose, as the actual list of TSAs changes fairly often and the EU TSL should be used as the authoritative reference). But the EU TSL only designates the specific TSU certificates as trusted, while for manual deployment (e.g. through Group Policy) it is usually better to deploy root or intermediate CAs.
