To support that we reuse the existing code in support for '%Z' specifier, for local_time_format, and produce output using singe format call with "[{0:%F %T},{1:%F %T},{2:%T},{3:%Q%q},{0:%Z}]" format string. As noted in the comment, produced output is locale independed, as it does not contain decimal separtors. For sys_info, the outputed literals are widended using _GLIBCXX_WIDEN, except opening and closing brackets, that are fetched from __format::_Separators.
