What is a time stamp?

Time stamp is a data which associated with or logically linked to an electronic document. Using time stamp allows to verify that the document is unchanged compared to the state at the time the time stamp is placed. Time stamp contains the imprint of the signature document and the time of the authentic and accurate clock of the trust service provider which was signed by the trust service provider thereby ensuring their consistency. As a result, it can be proved later and before a third party that the document existed at that time and in the given form.

Advantage of time stamping: If a document has both an electronic signature and a time stamp, then not only can evidence that the document be signed by the person whose certificate is included in the signature, but also that the document was signed before the date in the time stamp and has not changed since the signing.
