I asked a related question yesterday
http://stackoverflow.com/questions/2612343/basic-boost-date-time-input-format-question
It worked great for posix_time ptime objects. I'm have trouble adapting it to get Gregorian date objects.

try {
  stringstream ss;
  ss << dateNode->GetText();
  using boost::local_time::local_time_input_facet;
  //using boost::gregorian;
  ss.imbue(locale(locale::classic(),       
          new local_time_input_facet("%a, %d %b %Y ")));
  ss.exceptions(ios::failbit);
  ss>>dayTime;
} catch (...) {
  cout<<"Failed to get a date..."<<endl;
  //cout<<e.what()<<endl;
  throw;
}

The dateNode->GetText() function returns a pointer to a string of the form

The problem is I keep getting an exception. So concretely the question is, how do I go from const char * of the given format, to a boost::gregorian::date object?

Thanks again.
