Hi: I am working on a project whereby I need the date in the format yyyy-mm-dd (iso format). Am I write in thinking that the boost::Gregorian::to_Iso_string function will do this for me given a date as it's argument? I seem to have some discrepancies between the Embarcadero c++ 2009 implementation of that function and what I think should be happening having used the ms vc++ built version. Any help appreciated. Sean.
