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'.

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.

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.
Everyone agrees the atomic clocks run differently in space.(differently = at different proper rates)
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.
If the "atomic clock" is an SI-clock, this is wrong.
SI-clocks always run at the rate one second per second (1Hz).
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".
A second of "time" always lasts a second.
You can't measure the rate of a clock "in space"
with a clock on the Earth.

What does this statement mean?
Would "the motion of the Earth" not exist without the LT?
You are a master of stating meaningless statements.
The GPS has to communicate with the Earth.
So what?
Did you have a point with stating the bleeding obvious?
Seconds defined by SI are defined by atomic clocks,
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.
Then, you have no evidence of time dilation from the rate of theso atomic clocks
move at a different rate in space.
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?

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.
