title: What is the connection between LTV and document timestamps?
body: <p>I am confused about LTV in iText. I have read the paper, discussions but there is one thing still unclear. What is the connection between LTV and document timestamps? Or more precisely, how do I make pdf LTV enabled without using timestamps?
  One thing I know for sure, to make an LTV enabled document, I do not need timestamps. I tried signing a document with a digital certificate in acrobat and when opened it says the document is LTV enabled, I did not use any timestamp.</p>
