`template< class CharT, class Traits, class Duration > std::basic_ostream<CharT, Traits>& operator<<( std::basic_ostream<CharT, Traits>& os, const std::chrono::file_time<Duration>& tp );`		(since C++20)

Outputs tp into the stream os, as if by os << std::format(os.getloc(), STATICALLY-WIDEN("{:L%F %T}"), tp), where STATICALLY_WIDEN<CharT>("{:L%F %T}") is "{:L%F %T}" if CharT is char, and L"{:L%F %T}" if CharT is wchar_t.

Return value
