aperçu
C++ library for translating between absolute and civil times
historique
CCTZ is Google's C++ date, civil-time, and time-zone library for converting between absolute time and human civil time using IANA time-zone data. It is packaged both as a library and, in Homebrew, with the time_tool example executable.
The official repository was created in 2015. The README says CCTZ contains a Civil-Time Library and a Time-Zone Library that cooperate with C++ <chrono>, giving programmers tools for date, time, and time-zone work.
CCTZ had a v1.0 release in March 2016 and a v2.0 release in April 2016, followed by v2.1 in 2017, v2.2 in 2018, v2.3 in 2019, v2.4 in 2024, and v2.5 in 2025.
The README documents Bazel as the preferred build system while also supporting Make and CMake. The input package facts list Homebrew, Debian/Ubuntu libcctz-dev, Fedora/DNF, and Nix packages, showing adoption as a reusable C++ library rather than only as an application.
CCTZ is used by C++ programs that need correct civil-date arithmetic and conversion between time zones and absolute time points. The README points users to cctz/civil_time.h, cctz/time_zone.h, examples, Bazel, CMake, and system-installed IANA zoneinfo data.
CCTZ is package-nerd significant because time-zone handling is notoriously edge-case heavy, and this library packages a focused C++ solution around IANA data before broad standard-library time-zone support was common in deployed toolchains.
