13373	Warning in Boost.Log or Boost.DateTime with VS2017	christof.krueger@…	Andrey Semashev	"I'm getting the following compiler warning while compiling my code with VS2017 on a Windows 7 machine:

{{{
C:\Users\<...>\boost-1_65_1\boost/log/support/date_time.hpp(66): warning C4244: '=': conversion from '__int64' to 'uint32_t', possible loss of data
...
C:\Users\<...>\boost-1_65_1\boost/log/support/date_time.hpp(67): warning C4244: '=': conversion from '__int64' to 'uint32_t', possible loss of data
C:\Users\<...>\boost-1_65_1\boost/log/support/date_time.hpp(68): warning C4244: '=': conversion from '__int64' to 'uint32_t', possible loss of data

}}}

I'm using a simple console log (boost::log::add_console_log(std::clog)) wich a formatter created like this:

{{{
namespace expr = boost::log::expressions;
auto fmtTimeStamp = expr::format_date_time<boost::posix_time::ptime>(""TimeStamp"", %Y-%m-%d %H:%M:%S.%f"");
boost::log::formatter logFmt
    = expr::format(""[%1%] [%2%] {%3%} <%4%> %5%"")
        % fmtTimeStamp
        % expr::attr<my_severity_level_type>(""Severity"")
        % expr::attr<std::string>(""ThreadName"").or_default(std::string(""?""))
        % expr::attr<std::string>(""Channel"").or_default(std::string(""?""))
        % expr::message;
}}}

Is there anything I could do about? Or is it something that should be fixed within Boost? I'd like to have warning-free code wherever possible, of course."	Bugs	closed	To Be Determined	log	Boost 1.65.0	Problem	fixed
