Milestone:  To Be Determined                        |   Component:  date_time 
  Version:  Boost 1.48.0                            |    Severity:  Cosmetic  
 Keywords:  stream manipulator ptime setw           |  
----------------------------------------------------+-----------------------
 The following complete program demonstrates the issue.  when using
 operator<< to display a ptime/time_duration/date, then the setw()
 manipulator is ignored.

 My development environment is boost 1.48, building a 32-bit app on Win7
 (x64) under VS2008.

 I consider this a cosmetic issue as there is a very simple work-aroud -
 simply manually convert the ptime/date/duration object to a string before
 inserting it into the ostream object.

 {{{
 #include <boost/date_time/posix_time/posix_time.hpp>
 #include <boost/date_time/gregorian/gregorian.hpp>
 #include <iomanip>
 #include <iostream>
 #include <string>


 int main()
 {

     boost::posix_time::ptime const now =
 boost::posix_time::second_clock::local_time();

     std::cout
         << "\ncorrectly formatted: " << std::setw(40) <<
 boost::posix_time::to_simple_string(now)
         << "\nptime:               " << std::setw(40) << now
         << "\ntime_duration:       " << std::setw(40) << now.date()
         << "\ndate:                " << std::setw(40) << now.time_of_day()
         << std::endl;
 }
 }}}
