Time stamps are used to specify the date and time you signed a document. A trusted time stamp proves that the contents of your PDFs existed at a point-in-time and have not changed since then. Foxit PDF Editor allows you to add a trusted time stamp to digital signatures or documents.
To add a time stamp to digital signatures
To add a time stamp to digital signatures, a default time stamp server is required before you make the digital signature. If you have configured a default time stamp server and added it to your trusted certificate list, the time stamp will be embedded with the signature, and the signature properties will show the date/time in the time stamp server when you signed the document; otherwise, the signature properties will display the local date/time of the computer.
- Go to File > Preferences > Time Stamp Servers, and set a default time stamp server.
- Sign the document. See also Sign a PDF.
- You will be prompted with a pop-up Security Warning to ask you to allow connecting to your time stamp server. Click Allow.
- Then the signature you made has been successfully embedded with a timestamp. When validating the signature, users need to add the time stamp server into the trusted certificate list so that the signature properties will display the date/time in the time stamp server when the document was signed. See also Trusted Certificates.
Note: By default, if only one time stamp server is available in the system, it will be set as default automatically.
To add a time stamp to documents
- Before adding a time stamp to documents, you need to configure a default time stamp server. Click Protect > Time Stamp Document and create a timestamp server by clicking New… in the pop-up dialog box. Specify the server name and complete other settings of the server on demand. Click OK.
Select the created server and click Set Default to set the server as the default time stamp server. Click Next to continue.
(Tip: You can also create, edit, and delete time stamp servers as well as enable/disable the default time server in File > Preferences > Time Stamp Servers. To disable the default time stamp server, select the default time stamp server and click Clear.)
- Specify a name and location for the signed document. Click Save.
