Generally boost::posix_time imbues its own facet into the locale std::cout steam. So this facet remains reachable because AFAIK std::cout 
is not destroyed at all.

So if you do:

   std::cout.imbue(std::locale::classic());

Before return, no "leaks" would be at all.

Same as if you would write to any destroyable stream like std::ostringstream;

      std::ostringstream tmp;
      tmp << boost::posix_time::microsec_clock::local_time();
      std::cout << tmp.str() << std::endl;


So it is rather C++ design question why std::cout does not destroy its
own locale.
