AIUI, POSIX::strftime calls the function provided by the underlying OS. This is why the documentation makes the following recommendation. "If you want your code to be portable, your format (fmt) argument should use only the conversion specifiers defined by the ANSI C standard (C89, to play safe). These are aAbBcdHIjmMpSUwWxXyYZ%." As such, I probably wouldn't be considered a bug, at least not with the Perl distribution. So, unless you can persuade Microsoft to improve their POSIX support, you will have to restrict the format specifiers that you use on win32/win64 platforms to those specified.
