Can anyone tell me why the line:

time_period t4(t2);

in the attached cpp file doesn't compile but the line:

time_period t3(t1);

does? it seems like i should be calling the same copy constructor in
both cases but g++ 3.3.4 complains:

error: no matching function for call to `
   boost::date_time::period<boost::posix_time::ptime,
  
boost::posix_time::time_duration>::period(boost::posix_time::time_period

   (&)(boost::posix_time::ptime, boost::posix_time::ptime))'

   boost::date_time::period<boost::posix_time::ptime,
   boost::posix_time::time_duration>&)
/usr/include/boost/date_time/period.hpp:109: error:

  //why does this compile (on g++ 3.3.4)
  time_period t3(t1);
  //but this doesn't? i.e., why isn't a time_period a time_period a
time_period?
  time_period t4(t2);

  return 0;
