The inspection of the calculated Magnetic Local Time (MLT) values revealed that these values are not correlated to the time of day but rather incorrectly to the fraction of year.
This bug was traced to the original QD Fortran code (make_apex subroutine) where a decimal year values is incorrectly used instead of a Modified Julian Date (MJD) value.
