[boost] bug in boost/date_time/time_system_split.hpp - wrong static_cast

Hi there I've found a minor bug in time_system_split.hpp. In the following code date_duration_type day_overflow(static_cast<int_type>(doff)); int_type is __int64 if BOOST_DATE_TIME_POSIX_TIME_STD_CONFIG is on. But date_duration_type contructor expects int_adaptor<long> instead. So static_cast is useless here. I think, that right code should look like this: date_duration_type day_overflow(static_cast<date_duration_type::duration_rep_type>(doff)); Proposed patch's attached to this post. -- ______________________________ Vyacheslav E.
