PDF timestamping
You may want to sign and put a timestamp on your PDFs in order to give them a specific date. Most of PDF certificates include a timestamp service not guaranteed for low volumes.
TBS X509 Sign&Login and Email Professionnel certificates can timestamp PDF by using http://timestamp.comodoca.com/rfc3161
But, from a certain volume of signature, a timestamping local server can be needed.
