Of course they are, as they must always be. In fact it is the very idea
of a universal system of coordinates or timekeeping that is
"provincial." That is is childlike error that Gerald--

The 24 hour system,how each 24 hour cycle elapses into the next cycle
and subsequently how eqauble hours,minutes and seconds are derived
is so taken for granted that nobody really asks or cares where it all
comes from even though it is a huge achievement that belongs to many
civilisations over many millenia.

There is indeed a childlike element to it insofar as there is
absolutely nothing difficult and very much to enjoy about how the
daily noon correction keeps clocks fixed to natural noon -

The variations in length of the noon cycle and subsequently the noon
correction which keeps the 24 hour cycles ticking over was tampered
with in the late 17 century,one of the worst things was the
introduction of the 'analemma' hoax which assigns an importance to
variations in the Sun's position to the Equator,it turn the Equation
of Time from a global correction to a hemispherical mess -

Now you have huge problems for climatology because the pseudo-dynamic
of variable axial tilt is believed as a fact just as the equable noon
cycles are believed as a fact.




Where is the center of the Universe? Wherever the observer is standing.
What time is it, truly? Whatever time the observer thinks it is. Ask
a different observer, get a different answer. That is the true
universal truth--that there is no such thing as a universal time or
coordinate frame of reference.


I will tell you what there is and believe it like a man for a change.

The creation of the 24 hour day involves equalising the variations in
any given noon cycle to a standard pace,this pace we know as the 24
hour day and subsequently it generates equable hours,minutes and
secondsThe invention of clocks involved maintaining a standard pace
for as long as possible and the accuracy of these watches was tested
against the noon cycle by apply the Equation of Time correction -

'To reduce Watches to the right measure of dayes, or to know how much
they goe too fast or too slow in 24. hours.'

"Here take notice, that the Sun or the Earth passeth the 12.
Signes, or makes an entire revolution in the Ecliptick in 365 days, 5
hours 49 min. or there about, and that those days, reckon'd from noon
to noon, are of different lenghts; as is known to all that are vers'd
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 equall 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
shew'd by the Watches, though they be perfectly Iust and equal, must
needs differ almost continually from those that are shew'd by the Sun,
or are reckon'd according to its Motion. But this Difference is
regular, and is otherwise call'd the Aequation, and here you have a
Table, that shows it"

No doubt all the indoctrination of 'clocks measuring time' has
undermined your ability to appreciate how clocks measure distance
using the stable correlation where 4 minutes of clock time equal 1
degree of geographical seperation making 24 hours/360 degrees.

Whatever intellectual block involved in the inability to appreciate
how the noon corrected 'average' 24 hour day was transfered to the
axial cycle as a 'constant' thereby maintaining a 24 hour/360 degree
correlation there is absolutely no requirement to use clocks and
external references as Flamsteed and his contemporaries believed.
