Comment (by Jim King <jim.king@…>):

 I found that in time_resolution_traits the variable type being used is a
 boost::int32_t.  I changed this to std::time_t and the problems went away.
 This did require rebuilding some things.  I was able to simplify to_time_t
 and from_time_t down to:
 {{{
   //! Function that converts a time_t into a ptime.
   inline
   ptime from_time_t(std::time_t t)
   {
     return ptime(gregorian::date(1970,1,1)) + seconds(t);
   }

   //! Function that converts a ptime into a time_t
   inline
   std::time_t to_time_t(const ptime& pt)
   {
     return (pt - ptime(gregorian::date(1970,1,1))).total_seconds();
   }
 }}}
 What I am uncertain of is the effect this has on any backwards
 compatibility or i/o conversions for streaming.  Thoughts?
