Ask AI: What is a time stamp signer and what do they do

? A time stamp signer is a service that digitally signs documents and records and includes an accurate time stamp. This signature is then used as a way of verifying that the document existed at the time claimed. The signer provides a secure link between the document and its creator, as well as a guarantee that the document was not tampered with or altered during the signing process. This is useful for providing evidence in court and for other legal processes, as well as for providing a secure audit trail of all relevant documents.
