Detailed Description

Modified Julian Date wrapper (value type).

Wraps a raw double MJD value and provides conversions to/from UTC, JD, and arithmetic operations.

auto mjd = tempoch::MJD::from_utc({2026, 7, 15});
auto jd = mjd.to_jd();
auto mjd2 = mjd + 1.0; // next day
tempoch::MJD::to_jd
JulianDate to_jd() const
Convert to JD.
