What is Time ?

Time is a measurement that is constructed based on the rotation of the earth around it's axis and also by the revolution of the earth around the sun.

For many years humans have observed that the time taken for rotation of the earth is almost the same. This is observed by the time the sun rises. Similarly, the time it takes for the earth to revolve around the sun is also a constant. This pattern studied by humans for many years gave rise to the man-made construct called time.

Time is the same logical concept throughout the earth. There are different time zones based on the location and region of the earth. While one portion of the earth receives the daylight there is another portion of the earth receiving the moonlight at the same time.  

Time is not a concept that is the same at the Universal level. The time that we know is only specific to the laws of nature within the earth. If you move to another planet, the pattern of time becomes completely different from the pattern that we are aware of. This is because different planets have different times length of rotation and revolution. To understand this, let us consider 2 planets A and B. A person living on planet A will consider the time at planet B only with respect to the time at planet A. Similarly, a person living on planet B would measure the time of planet A only with respect to the time on planet B. 

1 day of time within a planet of a higher dimension can correspond to many days, months or even years within the planet earth. Such information can be seen in religious texts which speak of the big difference of time between the higher dimensions and the lower dimensions of the Universe. This can also mean that the stars we see during the nighttime are actually the state of the stars many years back. The reason for this is that the light energy from the stars can takes years of time to reach our naked eyes. Even the light energy from the sun takes 8 minutes to reach our eyes.
