Real lupnt::GetUt1UtcDifference(Real mjd_utc)

Get the UT1-UTC time difference at a given epoch.

Used by time-conversion routines (see conversions/time_conversions.cc) to convert between UTC and UT1 (e.g. for Earth rotation angle / sidereal time computations). Thin wrapper around GetEopData that extracts just the ut1_utc field.

Parameters:

mjd_utc – Epoch at which to evaluate UT1-UTC [MJD, UTC]

Returns:

UT1 - UTC [s]
