std::chrono::file_clock
Defined in header <chrono>
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

os
