std::chrono::sys_info(3)

📦 version 2024.07.05, in nixpkgs unstable, opensuse-leap 16.0

✨ NAME ✨

okay so bestie, welcome to the std::chrono::sys_info(3) page from the C++ Standard Libary manpage 💖 (that spelling is literally in the header, iykyk).

std::chrono::sys_info - std::chrono::sys_info

🌸 Synopsis 🌸

Defined in header <chrono> ✨

struct sys_info;            (since C++20)

The class sys_info describes time zone information associated with a time zone at a particular point in time (represented as either a std::chrono::sys_time or a std::chrono::local_time). This is a low-level data structure typically not used directly by user code. no cap, it's giving "plumbing, not main character energy" 🫶

🧸 Member objects 🧸

Member object — Type

  • begin, end — std::chrono::sys_seconds
  • offset — std::chrono::seconds
  • save — std::chrono::minutes
  • abbrev — std::string

The begin and end data members indicate the range - [begin, end) - in which the offset and abbrev are in effect for the time zone associated with this sys_info. 🌈

The offset and abbrev data member indicate the UTC offset and time zone abbreviation, respectively, in effect for the associated time zone and std::chrono::time_point. Note that time zone abbreviations are not unique. 💅

The save data member, if nonzero, indicates that the time zone is on daylight saving time at the specified time point. In this case, offset - save is a suggestion of what offset this time zone might use if it were off daylight saving time. However, this information is not authoritative: the only way to ascertain the actual offset is to query the time zone with a time point that is actually off daylight savings time (i.e. returns a sys_info such that save == 0min). 🫶
