[boost] [data_time] conversion warnings on 64bit platform

Hi, when using date_time on a 64bit windows platform i get a warning that a int64 value is converted to a long value in the following section: boost/date_time/time_system_split.hpp 189 typename date_duration_type::duration_rep_type doff = day_offset.add(td.ticks()); I use date_time with the BOOST_DATE_TIME_POSIX_TIME_STD_CONFIG macro set to get nanosec timer abilities (my own timers over the boost interface). Is this warning serious or can it be neglected? Regards -chris -- Christopher Lux | | Bauhaus-Universität Weimar | faculty of media - virtual reality systems group
