I think that is as it should be.  TAI time is a count of SI seconds from a
particular instant in time.  It is not divided up into minutes, hours,
days, months, years, etc. I realize that this is often done, but I believe
it to be not actually meaningful.  These terms apply to dynamical time and
also in a slightly different way to UTC, but they have little meaning for
TAI.
