SubjectWhy the time kept at the ISS is UTC? And Einstein's time?
Message-ID<99d6b19973967e9baf139c1ef2c16397@www.novabbs.com>
The International Space Station (ISS) uses Coordinated Universal Time
(UTC), also known as Greenwich Mean Time (GMT), as its standard time.
UTC is the scientific standard of timekeeping for the world and is based
on atomic clocks.

The ISS is a partnership between five space agencies from 15 countries.
The station is continuously operated 24 hours a day, 7 days a week, 365
days a year. Crews from the U.S., Russia, Japan, Canada, and Europe live
and work on the ISS, which orbits Earth every 90 minutes.

The shuttles also had UTC clocks so that the astronauts could easily
figure out what the "official" time aboard ISS was.

It's a compromise for the Americans and Russians. The crew day begins at
about two in the morning in Houston and ends at about eleven at night in
Moscow.


So, for ISS, t = t'. Einstein's SR time is not even considered, even
when there are several atomic clocks onboard.

More yet, any space vehicle used to transport astro/cosmonauts keeps
time using UTC/GMT.

Reality dictates that the world is used to t = t'.

EXAMPLE:


The Cassini space probe used:

- Spacecraft Event Time (SCET), also known as Orbiter UTC, to keep time.
SCET is the time at which an event occurs on the spacecraft.

- Coordinated Universal Time (UTC): The worldwide scientific standard
for timekeeping, based on atomic clocks.

-One-Way Light Time (OWLT): The time it takes for a signal to travel
from the spacecraft to Earth. From Saturn, OWLT can range from about 1
hour and 14 minutes to 1 hour and 24 minutes.

- Earth Received Time (ERT): The time the spacecraft signal is received
at mission control on Earth. ERT = SCET + OWLT.

Of course UTC is used in manned space crafts and space vehicles
that need to communicate with the Earth.

Yes, of course!

This is a meaningless statement.

The truth is that no clock which ticks out seconds as defined by SI
will stay synchronous with UTC, unless it is on the Earth's geoid.

This is so thoroughly experimentally verified that it can be
considered to be a fact, and nothing to discuss.

Of course, "local time" invented by relativistic
idiots is practically useless (and so is wannabe
second defined by SI).

Our dear nutters will know next year.

(atomic clocks to be placed on the ISS)

Of course they will scream false, swindle, and crazy about the results,
which you will hear about only from a bunch of swindling scientists,

Everyone agrees the atomic clocks run differently in space. It is absurd
to claim that means you can infer time runs differently. The rocket fuel
keeps burning at the same rate measured by Wozniak's clocks on Earth.

You can't measure the rate of a clock "in space"
with a clock on the Earth.

A wild, completely baseless assertion of a

According to relativists here recently, the LT must be required due to
the motion of the Earth, even though it is only 1/10,000th the speed of
light.

The GPS has to communicate with the Earth.

Seconds defined by SI are defined by atomic clocks, so atomic clocks
move at a different rate in space. Inferring that time runs at a
different rate is absurd. The rate of combustion of rocket fuel remains
the same.

What does this statement mean?
Would "the motion of the Earth" not exist without the LT?

You are a master of stating meaningless statements.

So what?
Did you have a point with stating the bleeding obvious?

Not quite.

SI has defined the time unit second like this:
"The duration of 9,192,631,770 periods of the radiation corresponding
  to the two hyperfine levels of the ground state of the Cs-133 atom."

A clock which ticks out seconds with the duration defined
above will in the following be called an SI-clock.

You probably meant to say:
  "atomic clocks run at a different rate in space"

If the "atomic clock" is an SI-clock, this is wrong.

SI-clocks always run at the rate one second per second (1Hz).
By definition!

> Inferring that time runs at a different rate is absurd. 

Right!

In physics, "time" must be measurable.
The instrument we use to measure "time" is by definition "a clock".
So (proper) "time" is what we measure with clocks.

A second of "time" always lasts a second.
Proper clocks (like SI-clocks) and thus "time" always run at
the same rate 1Hz by definition.


> The rate of combustion of rocket fuel remains the same.

Imprecise, but probably right.

If the rocket burns a constant amount of fuel per second,
the accelerating force will remain constant.

Did you think SR/GR claim otherwise?

But atomic clocks are not SI clocks, anyone can check GPS.
Your bunch  of idiots has no power to enforce your
idiocies  on the reality.

Wrong; that's true that they run one (second of a
relativistic idiot) per (second of a relativistic idiot),
but seconds are something else.

A lie, as expected from relativistic scum. There
is no such definition; and the main purpose of a
clock is  unrelated to your moronic physics. You
only imagine you're the center the world is
spinning around.



> A second of "time" always lasts a second.

But an SI second lasts a second on earth and
(9,192,631,770/9,192,631,774)  of a second in
a GPS satellite; anyone can check that.

Then, you have no evidence of time dilation from the rate of the
clocks—none at all from anywhere.

Here, Paul provides a good example of the deluded confusion of the
relativists.
If time itself dilated, then every rate of change would change in
unison, including the rate at which the fuel burns. It burns at the same
rate, so time does not dilate. What you are saying is the same as saying
the astronaut at light speed is not aging at a different rate. Make up
your mind. Relativity is so stupid and illogical.

Above I said several times that clocks and thus time always
run at their proper rate. "Time" doesn't "dilate".

Your response:

> relativists.

You don't read what you are responding to, do you? :-D
You didn't notice that we agree!

Right!

We agree that time doesn't "dilate".

You are wrong when you believe that GR say otherwise.

:-D

Pin this on the wall above your desk:

#          ACCORDING TO GR:                                #

############################################################

We don't agree about everything, though.

If I thought you were able to read a text,
I would have asked you to read this:

Pin that yourself, and then notice: clocks of
GPS  do not, they run 9 192 631 774 instead
9 192 631 770.
Good bye, The Shit, common sense was warning

For most practical purposes, the general relativity corrections to 
clocks on the ISS are irrelevant. Ordinary clocks are not even accurate 
enough for the corrections to be meaningful.

The corrections only matter when, well to pull an example out of thin 
air, you need to know exactly where satellites are and when signals were 
transmitted from them, so that you can calculate where you are on Earth 
based on the signals from several satellites.

There are NO general relativity corrections.
Your mad religion is forbidding them. That's
the whole concept of "time dilation": if
clocks desynchronize (what can be  no way any
surprise for anyone) - we may either assume it's
a  clock error  and correct them  - or assume
that's  exactly  what we need/expect from the
clocks  and  have  dilation.
Yes, Your time dilation is THAT stupid. That's
why common sense has been was objeting so
fiercely.
