Unfortunately Date::ISO8601::ymd_to_cjdn is much slower than
Time::JulianDay::julian_day:
Rate Date::ISO8601 Time::JulianDay Modified T::JD
Date::ISO8601 75997/s -- -73% -74%
Time::JulianDay 280501/s 269% -- -2%
Modified T::JD 287425/s 278% 2% --
(the last row/col is my optimised version of Time::JulianDay)
