11691,Boost.Log does not recognize file name pattern that includes datetime format specifiers,art.korotkov@…,Andrey Semashev,"Running the following example http://www.boost.org/doc/libs/1_59_0/libs/log/example/doc/sinks_xml_file.cpp with file name pattern ""%Y%m%d_%H%M%S_%5N.xml"" results log files having names like ""2015-Sep-29 08:42:02.330324"" (using Boost 1.59).

If datetime specifiers are not included in file name pattern, everything looks good. For example, running with file name pattern ""log_%5N.xml"" generates logs in form ""log_00001.xml"".

Compiling the same example with Boost 1.58 gives results as expected.",Bugs,closed,To Be Determined,log,Boost 1.59.0,Problem,fixed,"Boost, log, 1.59, file name pattern, datetime",
