Convert from Barycentric Dynamical Time Estimate to Julian date
returns an estimate of the Julian date for Barycentric Dynamical Time (TDB). These
estimations are valid for the years 1980 to 2050.jdtdb

[
additionally returns an array of Julian dates for the Barycentric Dynamical Time
(TDB) based on the Terrestrial Time (TT).jdtdb
