[Boost-users] date_time library problem

Hello,

here is a small piece of code that use the posix_time system that fails 
to compile.
I'm wondering whether it is a bug in the library or my usage of the 
library that is wrong.

Thank you for your help.

#include "boost/date_time/posix_time/posix_time.hpp"
#include <iostream>

int main()
{
   using namespace boost::posix_time ;

   ptime now = microsec_clock::local_time();
   std::cout << to_simple_string( now ) << std::endl ;

   return 0 ;
}

g++ -I/opt/boost brol.cpp
