Gravity slows time. Clock second hands and digital time piece seconds represent the measurement of the earth's gravity. Every second doesn't go any faster or slower. They are constant.

Deep inside the earth where gravity is concentrated time is a few milliseconds ( Mill lee from the standard metric system for a thousandth ) slower. On the surface, by the time you finish this sentence clocks tell us the future second has become the present and now the passed second. On the top floors of city sky scrappers a few microseconds ( micro from the standard metric system for a millionth ) faster.

The further we travel from the influence of the earth's gravity the more time speeds up. As we return to earth we are returning back to the influence of earth's gravity once more. Time slows down. By the time we reach earth we find time is the way we left it.

Quantum physics tells us every second is quantified. Quantum is a term meaning very tiny amount. It is 38 decimal zeroes, 6262 a total of a 43 decimal number of a meter. Such a tiny number is expressed as 6.262 times 10 to the minus 43. ( 6.626 X 10^-43 of a meter equivalent to 6.262 X 10^-36 of a millimeter called a Planck constant. In this case of time of a second called a Planck time.

Doing the math's if we remove the minis sign we have the same number in the positive value. ( 6.262 X 10⁴³ ).

It is the reciprocal of the minus value. Actually the minus value is the reciprocal of the positive value. In other words the reciprocal of each other. The positive value tells us tells us the number of Planck seconds in a second, while minus value tells us of a second. A theory the universe is made up of Strings exist on a scale this Planck scale. The Planck scale represents the amount of length, mass, time and energy.

Atoms are the smallest structure of the molecules that make up you and me. They are not the smallest by any means. Our atoms are made of further orbiting cloud of particles called electrons racing round a pair of particles in the center called neutrons and protons. These are made of a whole zoo of particles including quarks only to name one, ranging from up, down to strange Quarks. These particles are made of vibrating rubber band like strings that suppose to be no bigger than a Planck length in scale. Made up of these parts we are quantum on that tiny scale by nature.

Our environment second is made up 6.26 X 10⁴³ Planck seconds. It is the length of time frozen in time. The positive value tells us the number of times every second. It is a digital video equipment of a frequency of 6.262 X 10³¹THz ( tera from the standard metric system for 1 trillion and Hertz a single Planck second ) every second. Our eyes see a maximum of 20MHz ( Mega from for a million ) as perfect High Definition ( HD ) limit.
