std::chrono...zoned_time)(3)

💖 C++ Standard Libary — std::chrono...zoned_time)(3) 💖

hey bestie, welcome to the C++ Standard Libary manual page for std::chrono...zoned_time)(3) — yes, that’s the manual name and the page tag, and we’re about to get into std::chrono::operator<<(std::chrono::zoned_time). stay with me, it’s giving “niche chrono lore” and honestly it slays 💅

---

🌸 NAME 🌸

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

that’s the NAME, no cap — same function name listed twice, and we’re moving on 🫶

---

✨ Synopsis ✨

Defined in header <chrono>, bestie:

          Defined in header <chrono>
          template< class CharT, class Traits, class Duration, class
          TimeZonePtr >

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

                          const std::chrono::zoned_time<Duration, TimeZonePtr>&
          tp );

So this is since C++20, and the vibe is: it outputs tp to the stream os, as if by std::format(os.getloc(), fmt, tp), where fmt is "{:L%F %T %Z}" if CharT is char, or L"{:L%F %T %Z}" if CharT is wchar_t. literally that exact format string, don’t come for me 😭

🎀 Parameters 🎀

• os — output stream
• tp — zoned_time to output

---

💜 Return value 💜

• os — yep, it returns os, that’s the whole return value, periodt ✨

🦋 Example 🦋

This section is incomplete 😭

Reason: no example

ngl, no example here, that’s the tea 🍓

🩹 Defect reports 🩹

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

• DR — 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

that’s the whole defect-report moment, bestie 🔥
