Detailed Description

Umbrella header for the tempoch C++ wrapper library.

Include this single header to get the full tempoch C++ API:

• tempoch::Time<S> — split-storage instant on scale S
• tempoch::JulianDate<S> — JD encoding on scale S
• tempoch::ModifiedJulianDate<S>
• tempoch::CivilTime — civil UTC calendar label
• tempoch::TimeContext — explicit UT1 / historical UTC context
• tempoch::Period<T> — time period [start, end] with list operations
• tempoch::EopValues — IERS Earth Orientation Parameter values
• tempoch::eop_at() — interpolate EOP at a UTC MJD
• tempoch::eop_covers() — check EOP data availability
• tempoch::constants:: — named astronomical constants

#include <tempoch/tempoch.hpp>
 
auto utc = tempoch::Time<tempoch::scale::UTC>::from_civil({2026, 7, 15, 22, 0, 0});
auto tt  = utc.to<tempoch::scale::TT>();
auto jd  = tt.to<tempoch::format::JD>();
auto mjd = tt.to<tempoch::format::MJD>();
 
if (auto eop = tempoch::eop_at(mjd.value()))
    std::cout << "DUT1 = " << eop->ut1_minus_utc << " s\n";
 
std::cout << "J2000 = " << tempoch::constants::j2000_jd_tt() << " JD\n";
