There isn't any time flowing in those clocks, Grumpy. If it's a quartz clock it employs a piezoelectric vibrating crystal. If it's a mechanical clock it employs sprogs and cogs. If it's an optical clock it employs light emitted from a hyperfine transition. Whatever it employs, it goes slower when its slower because the thing it employs goes slower. It's that simple.
Clocks take a carefully measured cyclic process regulated by a process subject to time and count the cycles to measure the rate of time's passage. A muon created by the impact of a cosmic ray on oxygen molecules in the stratosphere is a clock, that muon has a fixed(in duration)time in which to exist before decaying into other particles. It's been measured with extreme accuracy in a lab at very low speeds. At near light speed they would only be expected to travel about a third of the distance to the ground in that amount of time(they can only go slower, going an even shorter distance). Why are those muons detectable at ground level?
Relativistic Time Dilation.
"It turns out that as an object moves with relativistic speeds a "strange" thing seems to happen to its time as observed by "us" the stationary observer (observer in an inertial reference frame). What we see happen is that the "clock" in motion slows down according to our clock, therefore we read two different times. Which time is correct??? well they both are because time is not absolute but is relative, it depends on the reference frame. Let's look at the following classic example. There is a set of twins, one an astronaut, the other works for mission control of NASA. The astronaut leaves on a deep space trip traveling at 95% the speed of light. Upon returning the astronauts clock has measured ten years, so yhe astronaut has aged 10 years. However, when the astronaut reunites with his earth bound twin, the astronaut he sees that the twin has aged 32 years! This is explained due to the fact that the astronaut's twin is traveling at relativistic speeds and therefore his "clock" is slowed down."

Your feet are younger(in total experienced time)than your head simply because, other than when supine, they spend much more time on the floor. Some physicists even consider gravity to be dilated time, mass dilates time and it becomes infinite at a BH singularity(in theory, anyway), where time stops. While it may forever be impossible for us to know, I think what is beyond that horizon is a wormhole back to the Big Bang...
No, scientific fact, your feet have experienced less time than your head, simply because your head is not as deep in a gravity well.
Time Dilation due to Gravity.
"Gravitational time dilation is at play for ISS astronauts too, and it has the opposite effect of the relative velocity time dilation. To simplify,
velocity and gravity each slow down time as they increase. Velocity has increased for the astronauts, slowing down their time, whereas gravity has decreased, speeding up time (the astronauts are experiencing less gravity than on Earth). Nevertheless, the ISS astronaut crew ultimately end up with "slower" time because the two opposing effects are not equally strong. The velocity time dilation (explained above) is making a bigger difference, and slowing down time. The (time-speeding up) effects of low-gravity would not cancel out these (time-slowing down) effects of velocity unless the ISS orbited much farther from Earth.
The key is that both observers are differently situated in their distance from a significant gravitational mass. The general theory of relativity describes how, for both observers, the clock that is closer to the gravitational mass, i.e. deeper in its "gravity well", appears to go more slowly than the clock that is more distant from the mass. This effect is not restricted to astronauts in space; a climber's time is passing slightly faster at the top of a mountain (a high altitude, farther from the Earth's center of gravity) compared to people at sea level. As with all time dilation, the local experience of time is normal (nobody notices a difference within their own frame of reference). In the situations of velocity time dilation, both observers saw the other as moving slower (a reciprocal effect). Now, with gravitational time dilation, both observers – those at sea level, versus the climber – agree that the clock nearer the mass is slower in rate, and they agree on the ratio of the difference (time dilation from gravity is therefore not reciprocal). That is, the climber sees the sea level clocks as moving more slowly, and those living at sea level see the climber as moving faster."
It's not my theory, it's Einstein's theory, and it isn't crap.
You don't even know the first thing about Relativity if you are claiming it contains anything but an invariant lightspeed.
"...the unsuccessful attempts to discover any motion of the earth relatively to the “light medium,” suggest that the phenomena of electrodynamics as well as of mechanics possess
no properties
corresponding to the idea of absolute rest. They suggest rather that, as has already been shown to the first order of small quantities,
the same laws of electrodynamics and optics will be valid
for all frames of reference for which the equations of mechanics hold good. We will raise this conjecture (the purport of which will hereafter be called the “Principle of Relativity”) to the status
of a postulate, and also introduce another
postulate, which is
only apparently irreconcilable with the former, namely,
that light is always propagated in empty space with a definite velocity c
which is independent of the state of motion of the emitting body. "

This is the first paper on Special Relativity, in Einstein's own words. If this disagrees with something he said prior to this, then this supersedes that prior statement or idea.
He went on to include in any gravity field or acceleration(which are equivalent, you know)in his paper on General Relativity.
Game, set, match.
