Date time documentation is so complicated and I can't find clear answer how to do that. Can you help me?
Yes, it's trivial, uses format flags like strftime -- see this doc page for more: http://www.boost.org/doc/html/date_time/date_time_io.html But here's some example code: #include "boost/date_time.hpp" #include <iostream> using namespace boost::posix_time; using namespace boost::gregorian; int main() { ptime t1(date(2007, Dec, 26), hours(1) + seconds(5) + milliseconds(9)); time_facet* timefacet = new time_facet("%a, %d %b %Y %H:%M:%S %z"); std::cout.imbue(std::locale(std::locale::classic(), timefacet)); std::cout << t1 << std::endl; //Wed, 26 Dec 2007 01:00:05 } Only thing to note there is that this doesn't output a timezone because the ptime type doesn't carry timezone data with it. To get the full timezone behavior you'll need to look up boost::local_time::local_date_time and the boost::local_time::local_time_facet. I trust you can look those up in the docs. Jeff
