[Boost-users] date-time separator

H all I am using posix time to print the current timestamp into a string. boost::posix_time::ptime now( boost::posix_time::microsec_clock::local_time() ); std::string nowString = boost::posix_time::to_iso_extended_string( now ); The output is the following being T the date-time separator 2002-01-31T10:00:01,123456789 Is there any way to change the 'T' char separator with another character or string? I need a space instead of a 'T' Thanks AFG
