The time stamp makes it possible to confirm the time when the electronic signature was placed, or to determine that a given document existed at a specific time and has not been changed. Under the provisions of applicable law, this has the effects of a certain date. The marker asks a dedicated server to obtain information about the time, then we get a guarantee that the date of signing the document will not be undermined. And this is an extra paid service.
By using a time stamp issued by a qualified entity, you get a guarantee that the deadline for signing the document will not be challenged in relation to: courts, institutions, companies, individual clients, etc.
