Add a timestamp to certificate-based signatures
You can include the date and time you signed the document as part of your certificate-based signature. Timestamps are
easier to verify when they are associated with a trusted timestamp authority certificate. A timestamp helps to establish
when you signed the document and reduces the chances of an invalid signature. You can obtain a timestamp from a
third-party timestamp authority or the certificate authority that issued your digital ID.
Timestamps appear in the signature field and in the Signature Properties dialog box. If a timestamp server is configured,
the timestamp appears in the Date/Time tab of the Signature Properties dialog box. If no timestamp server is
configured, the signatures field displays the local time of the computer at the moment of signing.
Note: If you did not embed a timestamp when you signed the document, you can add one later to your signature. (See
Establish long-term signature validation.) A timestamp applied after signing a document uses the time provided by the
timestamp server.
Configure a timestamp server
To configure a timestamp server, you need the server name and the URL, which you can obtain from an administrator
or a security settings file.
If you have a security settings file, install it and don’t use the following instructions for configuring a server. Ensure that
you obtained the security settings file from a trusted source. Don’t install it without checking with your system
administration or IT department.

URL. Specify whether the server requires a user name and password, and then click OK.
