boost-date-time

I need to get a nicely formatted timestamp (slightly modified ISO 8601) with millisecond precision. And example date would look like this: 2011-09-28 13:11:15.237-08:00 The formatting should be able to be overwridden as well. I've been playing around with boost::posix_time::microsec_clock::local_time() and boost::posix_time::time_facet which works just fine except when it comes to timestamps. Since posix time doesn't contain time zone information this is just not possible (I'm guessing) So, is there anything else I could use that has millisecond precision that contains timezone information or

I have the following code: #include <iostream> #include <string> #include <iomanip> #include <locale> #include <boost/date_time/gregorian/gregorian.hpp> #include <boost/date_time/gregorian/parsers.hpp> #include <boost/date_time/posix_time/posix_time.hpp> #include <boost/date_time/posix_time/posix_time_io.hpp> using namespace boost::posix_time; using namespace boost::gregorian; int main(int argc, char *argv[]) { std::string ds("2011-01-02"); date dt(from_string(ds)); date_facet *f=new date_facet("%Y-%m-%d"); std::locale loc=std::locale(std::locale::classic(),f); std::cout.imbue(loc); std::cout<

I'm using boost::date_time and I got a time_t, that have been generated by a library using the time() function from the C standard library. I'm looking for a way get a local time from that time_t. I'm reading the documentation and can't find any way to do this without providing a time zone, that I don't know about because it's dependant on the machine's locale, and I can't find any way to get one from it. What am I missing? For this task, I'd ignore boost::date_time and just use localtime (or localtime_r , if available) from the standard library. boost::posix_time::from_time_t() #include

My application requires custom time and date setting capabilities. I checked both ICU and boost::date_time libraries. Both appears to meet my requirements from a completeness point of view. I would like to know if there is any preference between the two and on what basis? which one will score on performance? Without more information about your specific use case and environment, there's no way to give a definitive answer as to whether either library out-performs the other. As Xeo suggested, profiling is the best way to address performance concerns. If your use case includes "general" date/time
