Well, I don't know what the problem is, but it isn't that the library 
restricts you to 24 hours.  If you look in test/posix_time/testduration.cpp 
you'll see this test:

   time_duration tdl2(2000000, 0, 0, 0);
   check("2000000 hours", tdl2.hours() == 2000000);

among others.  And it clearly passes on VC8. So, I think you must have a 
compilation problem or something else going on.

HTH,
