Default Neil DeGrasse Tyson headed down same loony road as Carl Sagan?

The fantasy based on absolute/relative time and its derivatives of absolute/relative space and motion is fairly straightforward and easy for anyone to understand.

The daily cycle, either natural or in terms of timekeeping, is anchored to noon so these followers running around chasing Newton's definition of the Equation of Time as absolute or relative time are as lovable as the late 17th century rogue.

"Absolute time, in astronomy, is distinguished from relative, by the equation of time. For the natural days are truly unequal, though they are commonly considered as equal and used for a measure of time; astronomers correct this inequality for their more accurate deducing of the celestial motions...The necessity of which equation, for determining the times of a phænomenon, is evinced as well from the experiments of the pendulum clock, as by eclipses of the satellites of Jupiter." Principia

All the crap about standing on the shoulders of intellectual giants is replaced by a few nuisances hiding behind a few 20th century characters who at least tried to escape the clockwork solar system (RA/Dec) and live in their heads instead.

Theorists don't get it for the real issues are with Huygen's description of the Equation of Time in tandem with the fractional year insofar as the Equation of Time only works with the 365/366 day/rotation system -

"Here take notice, that the Sun or the Earth passes through the 12 signs,
or makes an entire revolution in the ecliptic in 365 days, 5 hours 49
min. or there about, and that those days, reckoned from noon to noon,
are of different lengths as is known to all that are versed in
astronomy. Now between the longest and the shortest of those days, a
day may be taken of such a length, as 365 such days, 5. hours &c. (the
same numbers as before) make up, or are equal to that revolution: And
this is call'd the Equal or Mean day, according to which the watches
are to be set; and therefore the Hour or Minute showed by the watches,
though they be perfectly just and equal, must needs differ almost
continually from those that are showed by the Sun, or are reckon'd
according to its motion. But this difference is regular, and is
otherwise called the Equation of Time.." Huygens

Maybe people like the playacting which appears to give a certain group of people status they don't deserve. Physics would be fine with the 'astro' in front of it or that they consult with astronomers before dumping junk into the celestial arena as fact.
