Hello I want to output current date/time on my computer including timezone in this format: Date: Tue, 15 May 2007 09:21:48 -0400 -0400 is a timezone Im not really familiar with timezones and I could not understand the documentation how to output local timezone this way. Basically I just want to output local timezone on computer.. Heres what I have so far: #include <boost/date_time/posix_time/posix_time.hpp> #include <boost/date_time/local_time/local_time.hpp> #include <boost/date_time/local_time/posix_time_zone.hpp> #include <boost/date_time/date_facet.hpp> #include <ctime> #include <locale> #include <memory> #include <sstream> #include <boost/shared_ptr.hpp> std::string mystrftime(const std::string format, time_t time, const std::locale& locale = std::locale::classic()) { boost::shared_ptr<boost::local_time::time_zone> tz(new boost::local_time::posix_time_zone("dont know what to put here")); boost::local_time::local_date_time dt(boost::posix_time::from_time_t(time), tz); boost::local_time::local_time_facet *ff = new boost::local_time::local_time_facet(); ff->format(format.c_str()); std::stringstream s; s.imbue(std::locale(std::locale::classic(), ff)); s << dt; return s.str(); } int main () { std::cout << mystrftime("%A, %B %d, %Y %q", std::time(0)) << '\n'; } Thanks for help Regards A
