It's not really a problem.  With local_time you need to provide a timezone
pointer to get a time value.  So you call it like this:
  //get time in new york time zone:
  boost::shared_ptr<time_zone> ny_tz(new
posix_time_zone("EST-05EDT,M4.1.0,M10.5.0"));

  local_date_time ldt3 = local_microsec_clock::local_time(ny_tz);

You'll note that there is another overloading in clock classes for this case:

  template<class time_zone_type>
  static time_type local_time(shared_ptr<time_zone_type> tz_ptr);

If you want no adjustment from the machine, pass an empty shared ptr.
