Hi all, Sorry in advance if this is not the proper way for suggest a little patch... Compilation with VC71 raise tons of possible loss of data warning when using the microsec_clock::local_time() or universal_time(), warnings that can be avoided adding cast to (int) and to (boost::uint32_t) in: date_time\microsec_time_clock.hpp(156) date_time\microsec_time_clock.hpp(175) //The following line will adjusts the fractional second tick in terms //of the current time system. For example, if the time system //doesn't support fractional seconds then res_adjust returns 0 //and all the fractional seconds return 0. int adjust = (int)resolution_traits_type::res_adjust()/1000000; boost::uint32_t sub_sec = (boost::uint32_t)(filetime % 10000000) / 10; // microseconds What is the correct procedure to supply a patch? thanks in advance. --- Paolo Invernizzi
