What is Time?

Previous SubjectNext Subject
Hour Glass
Time is a period of time considered as a resource under your control and sufficient to accomplish something. An instance or single occasion for some event. A suitable moment. Regulate or set the time of. An indefinite period (usually marked by specific attributes or activities). The continuum of experience in which events pass from the future through the present to the past. A person's experience on a particular occasion.  A reading of a point in time as given by a clock. The fourth coordinate that is required (along with three spatial dimensions) to specify a physical event Rhythm as given by division into parts of equal duration.  Measure the time or duration of an event or action or the person who performs an action in a certain period of time. Assign a time for an activity or event. Set the speed, duration, or execution of. Adjust so that a force is applied and an action occurs at the desired time. "Temporary can be longer then you Think."

Time Perception

Time is the indefinite continued progress of existence and events that occur in apparently irreversible succession from the past through the present to the future.

Past is the time that has elapsed. Events which occurred before a given point in time. An earlier period in someone's life. History

Present is a period of time between the past and the future, now existing or happening now, the period of time that is happening now, the time that is associated with the events perceived directly and in the first time. Calendars

Future are events or states that have not yet happened, The time yet to come, Yet to be, what will happen in the time after the present. Its arrival is considered inevitable due to the existence of time and the laws of physics. Predictions

Impermanence is all temporal things, whether material or mental, are compounded objects in a continuous change of condition, subject to decline and destruction.

Space Time

Aeon is a relatively long period of time.

Great Year is the period of one complete cycle of the equinoxes around the ecliptic, about 25,800 years.

2012 Phenomenon was a range of eschatological beliefs that cataclysmic or otherwise transformative events would occur on or around 21 December 2012.

Clocks is an instrument to indicate time, keep time, and co-ordinate time. Any device for measuring time and displaying the time.

History of Timekeeping Devices


A Zeptosecond stopwatch for the microcosm Laser Physicists have recorded an internal atomic event with an accuracy of a trillionth of a billionth of a second. Zeptosecond is a unit of time equal to 0.000 000 000 000 000 000 001 seconds, that is, 10−21 second, and with symbol zs.

Orders of Magnitude (time) is a description of the quantity of a time in respect to comparison between differing magnitudes. In common usage, the scale is usually the base10 or base−10 exponent being applied to an amount, making the order of magnitude 10 times greater or smaller. As the differences are measured in factors of 10, a logarithmic scale is applied. In terms of time, the relationship between the smallest limit of time, the Planck time, and the next order of magnitude larger is 10.

Period is an amount of time. The interval taken to complete one cycle of a regularly repeating phenomenon.
A unit of geological time during which a system of rocks formed. The end or completion of something.

Milestone is a significant event in your life (or in a project).

Baby Milestones 

Juncture is an event that occurs at a critical time. A particular point in events or time. 

Critical Path Method

A crisis situation or point in time when a critical decision must be made.
The shape or manner in which things come together and a connection is made.

Regulated is to fix or adjust the time, amount, degree, or rate of. Shape or influence; give direction to. Controlled or governed according to rule or principle or law. Principles or usage. 

Standard Time is the synchronization of clocks within a geographical area or region to a single time standard, rather than using solar time or a locally chosen meridian (longitude) to establish a local mean time standard.

Space Time

Spacetime is any mathematical model that combines space and time into a single interwoven continuum, which is an involving gradual quantitative transitions without abrupt changes or discontinuities.

Space-time Continuum is a mathematical model that joins space and time into a single idea called a continuum. This four-dimensional continuum is known as Minkowski space, which is a four-dimensional manifold that has four dimensions: three dimensions of space (x, y, z) and one dimension of time.

Continuum (measurement) theories or models explains variation as involving gradual quantitative transitions without abrupt changes or discontinuities. In contrast, categorical theories or models explain variation using qualitatively different states.

is a continuous nonspatial whole or extent or succession in which no part or portion is distinct or distinguishable from adjacent parts.

Space-Time Crystal is a structure periodic in time and space. It extends the idea of a crystal to four dimensions. Analogues of the space-time crystal have been made that are in a non-equilibrium state that needs an external drive to repeat in time.

Spacetime Symmetries are features of spacetime that can be described as exhibiting some form of symmetry. The role of symmetry in physics is important in simplifying solutions to many problems. Spacetime symmetries are used in the study of exact solutions of Einstein's field equations of general relativity.

Wormhole or Spacetime Bridge, is a shortcut connecting two separate points in spacetime.

Timeline of the Far Future predicts how life will evolve over time; and plate tectonics, which shows how continents shift over millennia.

Temporal Paradox or time travel paradox is a paradox, an apparent contradiction, or a logical contradiction that is associated with the idea of time and time travel. Temporal paradoxes fall into two broad groups: consistency paradoxes exemplified by the grandfather paradox; and causal loops.

Time Dilation is a difference of elapsed time between two events as measured by observers either moving relative to each other or differently situated from a gravitational mass or masses.

Time Warp is the idea of changing the past is logically contradictory, and results in a grandfather paradox, which is a paradox of time travel in which inconsistencies emerge through changing the past. The name comes from the paradox's common description as a person who travels to the past and kills their own grandfather, preventing the existence of their father or mother and therefore their own existence. Any inconsistency in past events may be regarded as a grandfather paradox.

Time Perception

Everyone is a Time Traveler
You time travel when you think about your past Memories.
You time travel when you think about past events in History
You time travel when you plan for the Future.
You time travel when you talk to someone younger or older then you.
You time travel when you look at the stars at night.
Second chances happen all the time, it's called learning from mistakes.

Autonoetic Consciousness is the human ability to mentally place ourselves in the past, in the future, or in counterfactual situations, and to thus be able to examine our own thoughts. Our sense of self affects our behavior, in the present, past and future. It relates to how we reflect on our own past behavior, how we feel about it, and this in turn determines if we do it again.
Noetic is associated with or requiring the use of the mind.
Noesis is the psychological result of perception and learning and reasoning.

Will our Knowledge be Preserved?

Time is a Measurement System, a Process for Learning and a very important Tool that helps us Plan and Predict. Though the timing of Cycles, Rhythms and Development are essential for Life, try not to spend to much time thinking about Time, this is just one of many tools that we have.

Delta-T is the time difference obtained by subtracting Universal Time (UT) from Terrestrial Time (TT): ΔT=TT−UT. 

Time Dilation is a difference of elapsed time between two events as measured by observers either moving relative to each other or differently situated from a gravitational mass or masses. A clock at rest with respect to one observer may be measured to tick at a different rate when compared to a second observer's clock. This effect arises neither from technical aspects of the clocks nor from the propagation time of signals, but from the nature of spacetime.
Time Scale

Do you believe that time exists?

Time of Flight describes a variety of methods that measure the time that it takes for an object, particle or acoustic, electromagnetic or other wave to travel a distance through a medium.  Action Physics

Quasi-Biennial Oscillation is a quasiperiodic oscillation of the equatorial zonal wind between easterlies and westerlies in the tropical stratosphere with a mean period of 28 to 29 months.
Quasiperiodicity displays irregular periodicity. Periodic behavior is defined as recurring at regular intervals, such as "every
24 hours.

Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. The term vibration is precisely used to describe mechanical oscillation. Familiar examples of oscillation include a swinging pendulum and alternating current power. Hz

Arrow of Time involves the "one-way direction" or "asymmetry" of time. This direction can be determined by studying the organization of atoms, molecules, and bodies, and might be drawn upon a four-dimensional relativistic map of the world.

T-Symmetry is the theoretical symmetry of physical laws under a time reversal transformation.

Invariant Subspace of a linear mapping T : V - V from some vector space V to itself is a subspace W of V that is preserved by T; that is, T(W) - W.

CPT Symmetry is a fundamental symmetry of physical laws under the simultaneous transformations of charge conjugation (C), parity transformation (P), and time reversal (T). CPT is the only combination of C, P, and T that is observed to be an exact symmetry of nature at the fundamental level.

Fourth Dimension is required (along with three spatial dimensions) to specify a physical event.

A Timeline is a project artifact. It is typically a graphic design showing a long bar labeled with dates alongside itself. 

Units of Time (wiki)

86,400 seconds in a day. (1+8=9)
10,080 Minutes in a Day (1+8=9)
525,600 Minutes in a Year.

1,000 seconds is about 16 minutes.
A million seconds is about 11 days.
A billion seconds is about 32 years.

A second isn’t what you think it is. Scientifically, it’s not defined as 1/60th of a minute, but as “the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom”.

The Strontium Clock would neither gain nor lose one second in some 15 billion years.

Slave Clock is a clock that depends for its accuracy on another clock, a master clock. Many modern clocks are synchronized, either through the Internet or by radio time signals, to a worldwide time standard called Coordinated Universal Time (UTC) based on a network of master atomic clocks in many countries.

The smallest standard scientific measure of time is the “Planck time”. It takes you about five hundred and fifty thousand trillion trillion trillion Planck times to blink once, quickly.

Time is measured by one complete Orbit around our Sun, which is called one Year. A 12 month calendar, which equals one year (365 Days, or 365 Earth Rotations), is an incremental tool which divides one earth orbit around our sun into Months and Days. Time is also measured by one complete rotation of the earth, which is called one day. A 24 Hour Clock is an incremental tool that divides one rotation of the earth into Seconds, Minutes and Hours. Time is also measure by Carbon Decay, which is then calculated into how many earth orbits around the Sun.

Time Visual
Cycles is an interval during which a recurring sequence of events occurs. A periodically repeated sequence of events.


Time Perception

Time Perception refers to the subjective experience of life: time, which is measured by someone's own perception of the duration of the indefinite and unfolding of events.

Frame Rate

Slow Motion Perception is a postulated mental state wherein time seems to be slowed down. People experiencing life-threatening situations sometimes report that time seemed to have slowed down.

Areas of the Brain that Process Time

Time goes Faster when you're busy and happy.
Time goes Slower when you're bored, unhappy and not busy.

Busy is being active or fully engaged or occupied. Characterized by much activity.

"Life starts out slow then life gradually speeds up because we add more things into our timeframe, which sadly makes us pay more attention to time then life itself."

Time is related to the speed at which our Earth turns, and since most planets turn or rotate at different speeds, our perception of time and measurement of time is only unique to Humans on Earth.

New experiences really do seem to be longer in the memory than familiar ones. It’s called the “oddball effect”, and it seems to be why time feels like it’s going faster as you get older – because more stuff is familiar to you.  

Oddball Paradigm is an experimental design used within psychology research. Presentations of sequences of repetitive stimuli are infrequently interrupted by a deviant stimulus. The reaction of the participant to this "oddball" stimulus is recorded.

Take a day off, take a break, pause, unwind, regroup and relax.

Can I make up for lost time?

Humans have a startling accurate sense of time, particularly when younger. The mechanism we use for this seems to be a distributed system involving the cerebral cortex, cerebellum, and basal ganglia. Long term time keeping seems to be monitored by the suprachiasmatic nuclei (responsible for the circadian rhythm). Short term time keeping is handled by other cell systems.

"Tomorrow is not a mystical land where 99% of all human productivity, motivation and achievement is stored, that's today, so why wait?" 

Don’t say "I don’t have enough time". You have exactly the same number of hours per day that everyone else has, well almost everyone. Instead of saying "I don't have the time", you could say, "I currently have other responsibilities and other people are counting on me to fulfill those responsibilities, but when those commitments change, I would like to know more about what you do, as well as the ways that I could help you".

Time Management is an extremely important tool when it comes to planning and predicting. But we cannot allow time to dictate and control all of our actions all of the time, if we did, we would disconnect from ourselves and reality, and become more machine like then human. We have to relax and connect to our inner self a couple of times a day. We have to separate our external time from our internal time. We need time to ourselves, where time has no meaning, and our mind is free to wander.

"You don't want to rush into things, and you don't want to move to slowly either."

Action Physics

Even when I'm doing all the things that I can, I still feel sometimes like I'm not doing enough, like there's another level of productivity that I haven't reached yet, where time management becomes more machine like, where every minute is correctly, effectively and efficiently calculated and divided up in a way that I can complete as many tasks that I can in one day. But I must do this without having time interfere with life, or have time interrupt life, or have time diminish life. So within that machine like management of time there has to be time set aside to just think and reflect, or you may risk not having a life, and not feel alive, or even feel human. 

Time is of the Essence

"There are many things in my life that I am not totally in control of. Even though I am getting better at controlling things in my life, I am still not in control of everything. I prioritize, but I have to learn how not to ignore things that still may be important. So I have to learn how to spend some more time on the lower priorities in my life, because they still may have significance. How many things do I need to be in control of in my life in order to feel that I am in control of my life? Without turning into a Control Freak or becoming a Perfectionist."


If you live to be 100 years old you'll live 876,000 hrs. in your life. Minus 300,000 hrs. sleeping, minus 73,000 hrs. eating, minus 120,000 hrs. working, minus 20,000 hrs. of school and so on. That leaves you less then 400,000 hrs. to do what you want, that's if you live to 100 in good health?

Daylight Saving Time is the practice of advancing clocks during summer months by one hour so that evening daylight lasts an hour longer, while sacrificing normal sunrise times. Typically, regions with summer time adjust clocks forward one hour close to the start of spring and adjust them backward in the autumn to standard time.

Can you really turn back time?

Studies show that there is an increase in both heart attacks and road accidents the days after clocks are set forward one hour in Spring. Losing one hour of sleep disrupts the Body Clock. Being tired can decrease productivity, concentration and general well-being. Children may feel tired and cranky for several days after an hour's change in their bedtime routines. There doesn't seem to be any health benefits to daylight savings time, so what do we need it for? And do the reasons out weigh the adverse effects.

Value of Time is the opportunity cost of the time that a traveller spends on his/her journey. In essence, this makes it the amount that a traveller would be willing to pay in order to save time, or the amount they would accept as compensation for lost time.

Are we frozen in time, or are we moving?
Let go of the concept of time as if time did not exist. Now imagine the past, the present and the future being the same thing, occupying the same space. Now look out at the stars at night, you see the past, the present and the future, all at the same time. Now stay there for a moment, think, experience life without time.....can you explain it?

Suspended Animation is the slowing or stopping of life processes by exogenous or endogenous means without termination. Breathing, heartbeat, and other involuntary functions may still occur, but they can only be detected by artificial means.

Time (poem)
Time can be seen and time can be felt.
Through the years of changes our world has endured,
through the changes we experience in ourselves.
Measured by moments and the rising of our Sun,
it's the one thing we can be thankful for when the day is done.

"We have all had moments where we have helped someone in need, maybe saving someone's life, and we remember how great we felt because we know we did something that was needed, something that was special, because we know how important help can be to someone in need. I'm in one of those moments right now, except this is one big moment, a much larger picture, a moment stretching many lifetimes and encompassing many moments in time, eons. Except this type of time is not measured by our sun, this time stretches across the universe. Time on earth has been slowed down, giving humans a chance to see and experience life in a unique way. But our experience of time is only unique to earth. Beyond our planet time takes on a whole new meaning where time is not measured in seconds, hours, days or years, in fact it's not a measurement at all, time is something that is felt and experienced, which transcends all definitions of time and our understanding of what time is. It is the ultimate moment."

I don't dream about the future, the future dreams about me, and the future is smiling. The past is also smiling, because the past knows how far I've come and also sees what I'm doing now. We're halfway home.
