tempoch-cpp

Why it exists

tempoch-cpp brings the tempoch time model into C++ as ordinary value types. It covers Julian dates, MJD, UTC, and periods without forcing C++ users to think in FFI terms.

Key Features

• JulianDate and MJD strongly-typed value wrappers
• UTC civil date-time with nanosecond precision
• Period intervals with intersection operations
• Exception-based error model (typed C++ exceptions)
• CMake integration with automatic Rust FFI build

Getting Started

// CMakeLists.txt
find_package(tempoch_cpp REQUIRED)
target_link_libraries(myapp PRIVATE tempoch::tempoch_cpp)

// main.cpp
#include <tempoch/tempoch.hpp>
using namespace tempoch;

auto jd = JulianDate::from_utc({2026, 1, 1, 0, 0, 0});
auto mjd = MJD::from_jd(jd);
auto utc = jd.to_utc();
