std::time_t(3)

okay so bestie 💖, this is the std::time_t(3) page from the C++ Standard Libary manual, and time_t is lowkey having a main character moment. let's get into it ✨

✨ NAME ✨

• std::time_t — std::time_t (that's the whole name, bestie, no notes 💅)

🦋 Synopsis 🦋

here's the vibe check on where it lives and what it looks like:

Defined in header <ctime>
typedef /* unspecified */ time_t;

so time_t is an arithmetic type capable of representing times ✨

the exact type is not defined, but it's almost always an integral value holding the number of seconds — and no, we are not counting leap seconds 😭 — since 00:00, Jan 1 1970 UTC, corresponding to POSIX time. that's the origin story, periodt.

the girlies in the same friend group are:

• time — returns the current time of the system as time since epoch (function)
• localtime — converts time since epoch to calendar time expressed as local time (function)
• gmtime — converts time since epoch to calendar time expressed as Universal Coordinated Time (function)
• to_time_t — converts a system clock time point to std::time_t — [static] (public static member function of std::chrono::system_clock)
• C documentation for time_t
