I am always amazed when people superfluously use new.  I am willing to
bet that superfluous use of new is responsible for quite a number of
C++ memory leaks and heap thrashing.  Try:

int main()
{

   ptime t1(date(2007, Dec, 26), hours(1) + seconds(5) + milliseconds(9));

   time_facet timefacet("%a, %d %b %Y %H:%M:%S %z");
   std::cout.imbue(std::locale(std::locale::classic(), &timefacet));

   std::cout << t1 << std::endl; //Wed, 26 Dec 2007 01:00:05
}
