Hi Chris -

Sorry for the slow reply.  Indeed, from_iso_string only handles non-delimited 
iso format.  That is:

   std::string s("19991217T151515");
   ptime t = from_iso_string(s);

Couple possibilities.  1) strip the '-' and ':' chars before you call 
from_iso_string.  2) Use the streaming operators with iso extended mode:

   std::stringstream ss;
   time_input_facet* input_facet = new time_input_facet();
   input_facet->set_iso_extended_format();
   ss.imbue(std::locale(ss.getloc(), input_facet));
   ss.str("1999-12-17T15:15:15");
   ptime t1;
   ss >> t1;
