C-style date and time

template <class CharT, class Traits> std::basic_ostream<CharT, Traits>& operator<<(std::basic_ostream<CharT, Traits>& os, const std::chrono::weekday_last& wdl);		(since C++20)

Outputs a textual representation of wdl into the stream os, as if by os << wdl.weekday() << "[last]";.

Return value

os.

Notes

This operator<< is primarily intended for debugging use. When used with non-default stream flags, the output may be surprising:

auto wdl = std::chrono::Sunday[std::chrono::last];
std::cout.width(10);
std::cout.fill('-');
std::cout << std::left << wdl; // may output "Sun-------[last]"
