Milestone:  Boost 1.39.0          |   Component:  date_time

----------------------------------+-----------------------------------------
 The constructors for boost::posix_time::hours, minutes, and seconds take
 arguments of type long, which is 64 bits on 64 bit LP64 environments like
 MacOS 10.5. This leads to warnings about possible truncation when these
 arguments are passed to the constructor for time_duration. Since
 time_duration is a template class that can be instantiated for different
 types, boost::sint32_t seems like a safer type to use in the non-templated
 constructors in boost::posix_time than a compiler-specific type like long.

     {}
   };
