std::chrono...::file_time)(3)

🌸 NAME 🌸

okay so this page is std::chrono...::file_time)(3), from the C++ Standard Libary manual (yes, “Libary” — that’s literally the manual name, not me 💀), and it’s all about std::chrono::operator<<(std::chrono::file_time). NAME says std::chrono::operator<<(std::chrono::file_time) — and then says std::chrono::operator<<(std::chrono::file_time) again. Self-referential queen behavior, honestly 👑.

✨ Synopsis ✨

Defined in header <chrono>:

template< class CharT, class Traits, class Duration >

std::basic_ostream<CharT, Traits>&                             (since C++20)
    operator<<( std::basic_ostream<CharT, Traits>& os,

                const std::chrono::file_time<Duration>& tp );

So this operator 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. Literally the whole vibe, bestie 🫶.

💖 Return value 💖

os. That’s the return value. That’s it. Slay ✨.

🔥 Defect reports 🔥

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

• P2372R3 — applied to C++20. Behavior as published: the given locale was used by default. Correct behavior: L is needed to use the given locale. 💅
