Timestamp request

[WindowsNT]

Hello, the library is excellent,I use it in my apps that require client side signing. However I have a request. It is essential for both plain pkcs#7 messages and PDF signing to include a timestamp from a trusted rfc 3161 provider, this can be added as an unauthenticated parameter to any cms. forge cannot do it, but you may want to check https://github.com/kjur/jsrsasign which provides timestamping classes.
