The Perfect Clock

Could they build a perfect clock?

Current clocks use a frequency or vibration that can be
affected for the speed and gravity. Time wouldn't be relative
if they used a perfect clock.
 
No. The construction of the clock has no bearing on time dilation due to either relative motion or position in a gravity field. All having a "perfect" or ideal clock would do is allow us to measure it more accurately over smaller relative velocities and smaller gravitational potentials.

Your clock assumes an outdated Newtonian universe, where there is some sort of absolute time and preferred frame of reference. These are both factually incorrect.

The very idea of a perfect clock is contradictory. There is no absolute time that it could measure, even in principle - and there is no preferred frame of reference. All frames of reference are relative. And all FoRs (that are not co-moving) will keep different times.

We live in an Einsteinian relativistic universe.

Hell, I misread it. I thought you said the perfect Glock.

I was going to argue that it doesn't exist as well, but for vastly different reasons...
 
I misread perfect cock. For some reason.
Like a cock that can fight, lay eggs and wake you in the morning?
Cock magic might be on the wish list too...

IDEA OF MEASURING CHANGES ) DESIGN OF A CLEPSYDRA
A clock is a device whose functioning is correlated with the configuration of the
Sun and Earth (Fig. 3.1). When used as clocks, the rhythms of nature do not
generate time. A clock does not produce time and it does not consume time; the time displayed is subject to strict international conventions. The idea (concept) of measuring changes (phenomena) is made concrete by the invention of the clock (artifact): this is conception or design, i.e., the materialization of a concept through
the gnomon, sundial, clepsydra, and clock. Consider what Petronius (?–65 AD)
said: … a clock near which a “bucinator” (latin word for a “trumpet player”) warns
us of the flight of the days, and time gone by ([11]: XXV).
Days and hours cannot be measured; it is changes that are measured.
IDEA OF MEASURING CHANGES = MAKING A CLOCK

Therefore, a consistent definition of the second is

THE SECOND IS A UNIT CORRESPONDING
TO 9,192,631,770 CESIUM CYCLES

This definition of the second does not go against the provisions of the Conferences of 1967 and 1983, including reference to cesium frequency; but its wording has the advantage of not using the word duration. In addition, this definition emphasizes that the international unit of time has no physical existence

In 2011, a British clock reached an accuracy of 2.3 10−16 s, which is an error of 1 s/138 million years. It illustrates the considerable role of high technology and state-of-the-art physics. The leap second between solar time and atomic time requires periodic resynchronization: if time was a physical component of nature, such questions would obviously not arise. The accuracy of measurements is determined by the accuracy of clocks; but the accuracy also depends on the rigor of the definition of the second.
Terrestrial rotations, terrestrial revolutions, and the cesium oscillations, produce observable and measurable cycles, but they do not produce time; even if a misleading field effect suggests the idea of an arrow of time

Both extracts from

The Invention of Time and Space by
Patrice F. Dassonville

If you wish to know about time and clocks I recommend this book. Very detailed in parts but understandably with the contention time does not exist

Well that sort of cock, certainly, but rather as in the UK expression "a load of cock", being short for "a load of cock and bull", as in a "cock and bull story", viz. a sort of highly fanciful agricultural story - or the ideas of someone who has spent a while drinking in the cock and bull pub .
 
The first step towards the perfect CLOCK is the cosmic CLOCK (Sun - Earth system)
The Sun can't be in two positions at a time in the sky. One for the observer on the
ground and one for the observer traveling in space.

Except that, according to an observer far out in space, the Sun WILL be in a different position from that seen by an observer on Earth.
So - as usual - you've failed again.
 
I find you 'funny' too.

You might want to look up gravitational lensing before you declare that the sun could be a perfect clock by the way.
Not only that, but the surface of the sun is in constant motion. A clock based on "the position of the sun in the sky" won't be very accurate because of this.

The perfect clock doesn't have to be very accurate.
This clock measures an absolute time.
