Adding timestamp from P7S file

Hi,

I'm trying to add a timestamp to a signed pdf following the examples here:
https://svn.apache.org/viewvc/pdfbox/trunk/examples/src/main/java/org/apache/pdfbox/examples/signature/TSAClient.java?revision=1792644&view=markup

Using a service like FreeTSA, which follows RFC 3161, is working fine for
me.

However, the paid provider I have returns timestamps via P7S files, which
I'm assuming are PKCS (Public-Key Cryptography Standard) #7 format files.

Is there any way to extract the information from the P7S file and put it in
a format such as the one expected by TSAClient?

I'm attaching below the base64 representation of the timestamp file (p7s) I
have:
