std::chrono...k::from_utc(3)

💅 std::chrono...k::from_utc(3) — C++ Standard Libary

okay so bestie, welcome to the C++ Standard Libary manual 💖 today's main character is std::chrono::tai_clock::from_utc, and she is literally here to clock-convert your UTC vibe into TAI time. no cap. 🕰️✨

🌸 NAME 🌸

• std::chrono::tai_clock::from_utc — yep, that's the whole name: std::chrono::tai_clock::from_utc. iconic, repetitive, we love her. 💅

🦋 Synopsis 🦋

here's the full signature, copied with love and zero edits:

          template< class Duration >

          static std::chrono::tai_time<std::common_type_t<Duration,
       (since C++20)
          std::chrono::seconds>>

              from_utc( const std::chrono::utc_time<Duration>& ) noexcept;

the way this function just converts the utc_time value named t into a tai_time representing the exact same point in time? obsessed 😭🔥

💖 Return value 💖

you get back a std::chrono::tai_time representing the same point in time as t, computed as if by constructing a value of the return type from t.time_since_epoch() and adding 378691210s. and yes, 378691210 is the number of seconds between the epochs of the two clocks: 1958-01-01 00:00:00 TAI and 1970-01-01 00:00:00 UTC. epoch math moment 🧚✨
