std::chrono::operator<<(std::chrono::year) - std::chrono::operator<<(std::chrono::year)


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

Forms a std::basic_string<CharT> s consisting of the year value stored in y formatted as a decimal number, left-padded with 0 to four digits if the result would otherwise be less than four digits. Inserts that string into os. Then, if !y.ok(), inserts the string " is not a valid year" into os.

Return value



This operator<< is primarily intended for debugging use. For control over formatting, use std::chrono::format.
