Bulletin C 33
To authorities responsible
for the measurement and
distribution of time
INFORMATION ON UTC - TAI
NO positive leap second will be introduced at the end of June 2007.
The difference between Coordinated Universal Time UTC and the
International Atomic Time TAI is :
from 2006 January 1, 0h UTC, until further notice : UTC-TAI = -33 s
Leap seconds can be introduced in UTC at the end of the months of December
or June, depending on the evolution of UT1-TAI. Bulletin C is mailed every
six months, either to announce a time step in UTC, or to confirm that there
will be no time step at the next possible date.

'Leap seconds' must sound great to those who know no better but it has
none of the pedigree of the ancient timekeeping system which keep
clocks in sync with axial rotation at precisely 4 minutes for each
degree of rotation.
Had one person appreciated how the equable 24 hour day was a product
of reducing the variations of the natural day to a 24 hour day and
then when axial rotation was discovered,the technical feat of allowing
24 hours to elapse seamlessly into the next 24 hours was transfered to
the principle that axial rotation and clocks remain always in sync at
15 degrees per hour and 24 hours through 360 degrees.
The principle of leap seconds is little more than empirical
fundamentalism,the inability to appreciate that there are 86 ,400
seconds added every 4th year in order to break the celestial sphere
cycle into 3 sections of 365 days and 1 section of 366 days. |

Do you honestly believe the earth rotates exactly 360 degrees in 24
hours?
I've asked you this question several times. You always ignore it.
Sometimes you reply a long nonsense post, but this calls for one
word. Yes or no - do you honestly believe the earth rotates exactly
once in 24 hours?

Do you honestly believe the earth rotates exactly 360 degrees in 24
hours?
Do you know what the word 'correlation' means ?.
Do you know how the pace of a clock hour,minute and second correlates
with axial rotation in terms of longitudinal seperation based on 4
minutes for each degree of geographical seperation making 24 hours/360
degrees ?
Do you understand the difference between the clock/axial rotation
correlation and axial rotation as an indepedent principle ?.Do you
understand why the clock/axial rotation correlation is seperate to
whether the Earth's axial rotation is constant ?.
Do you understand that the human devised principles for the equable 24
hour day does not require an external reference and there is none to
be found hence the Equation of Time ?
Do you clearly understand that the noon Equation of Time correction
keeps the 24 hour day constant and seamlessly elapsing into the next
24 hour day ?
Do you clearly understand that Copernicus discovered axial rotation
causes the daily cycle ?
Do you understand how the heliocentric astronomers made excellent use
of the older principles which create the equable 24 hour day,how they
just overlayed the principles which create the 24 hour day on top of
terrestrial longitudes ?.
Do you understand that in order for the clock/axial correlation to
work,the Equation of Time had to be applied ?
Considering that it is many years since I actively promoted the
astronomical timekeeping system which keep clocks in sync with axial
rotation and I have still to see one person here grasp the basics,even
when most have heard how clocks resolved longitude.

The value which you assign to axial rotation and the justification is
outright fundamentalism,worse still,it appears to be in the majority -

It costs nothing for genuine astronomers to appreciate the actual 24
hour/360 degree correlation between clocks and axial rotation,its
originas are from the deepest and most ancient of traditions of
astronomy and its heliocentric adaption to axial rotation matches it.
The false conception via Flamsteed is based on a 1461 day calendar
cycle and it would be a badge for a genuine astronomer to know how Not
to justify the axial and orbital motion of the Earth through celestial
sphere geometry
http://hypertextbook.com/facts/1999/JennyChen.shtml
http://www.pfm.howard.edu/astronomy/Chaisson/AT401/IMAGES/AACHCIR0.JPG
An accurate relationship betwen axial and orbital motion is
desperately required for climatological purposes,to retain a really
obstructive idea for axial and orbital motion is way beyond
irresponsible,it is downright fundamentalist.
You can have your damn celestial sphere geometry once you know how not
to use it but official policy still uses it to explain the Earth's
axial and orbital motions.Neither the appeal to you as parents,as
people with genuine concerns for the planet or anything else seems to
move you in the direction of a magnificent shared astronomical
heritage. |

If you look at Oriel's responses it has all the hallmarks of some sort of
bot responding with canned paragraphs to certain keywords. I suspect it is
more someones idea of a joke than a kook. I will try to lay some bait:

Yes.

Yes. 24 hours in 360 degrees of longitude. 23 hours, 56 minutes, and
4.x seconds in 360 degrees of rotation.

Nonsense. The 24 hour clock is based on the sun - an external
reference.

I thought there was no external reference...
Quote: Do you clearly understand that Copernicus discovered axial rotation

Yes. Anyone who has completed third grade knows that. Miss Decker
had a model of the solar system, and she could turn a crank and all
the visible planets (and the moon) would rotate and revolve
approximatly at rates relative to what they do in space. It's
something any third grader can understand. But you are still stuck in
third grade.

Yes. But they knew more than you do, including that a day is not a
rotation.

You keep blabbing on about the equation of time. If it's an equation,

As expected, a non-answer. Don't call on your Christianity (or attack

I've always reckoned that we should decimalize Time keeping.........
Lets face it.......the French have decimalised just about every other common
measure......mass, length, speed, volume........why not time??
At university they were always banging on about using SI........except for
time.........
