Hi all, I'm trying to use the date time library to to do some string formatting but I'm afraid there's something I'm missing. What I'd like to do is feed in a string "05/Aug/2007 11:30" and convert it to an ISO formatted string - could anyone point me in the right direction? I've examined both the documentation and the sample code in io_tutorial.cpp but I'm afraid it hasn't helped - the code below is as far as I've gotten and simply returns the input string unchanged. I'm using boost 1.34.1 with MSVC 2005. Thanks much, Andrew //Begin snippit string formatDate(string inpDate) { stringstream ss; local_date_time checkDate(not_a_date_time); local_time_input_facet* input_facet = new local_time_input_facet(); local_time_facet* output_facet = new local_time_facet(); ss.imbue(locale(locale::classic(), output_facet)); ss.imbue(locale(ss.getloc(), input_facet)); input_facet->format("%d/%b/%Y %H:%M"); output_facet->set_iso_format(); ss << inpDate; return ss.str(); }
