GNU C library compatible strftime for loggers and servers
POSIX::strftime::Compiler provides a GNU C library compatible strftime(3), which is not affected by the system locale. This is useful when you want to write loggers, servers and portable applications that generate the same result strings on any locale. Technically, POSIX::strftime::Compiler wraps POSIX::strftime and converts some format characters to perl code.
