Is there any helper function to convert boost::posix_time::ptime to FILETIME?

I am trying to pass datetime value from boost-based app to another (C#).

Looks

like that FILETIME (that can be represented as long) is a good option, besides string. May be there is better alternative?

I am getting better and better in answering my own questions :)). I apologize for the original post.
