Although it's not an easy task to define time. But apparently is seems that if we have information at one end of the system and depending upon the system properties at the other end, we can see change; that is reflection of system properties. Let's us assume if system does not affect information at all so it does not matter how much so-called time passes, we will have same information at the other end of system. Similarly, events occur only due to manmade or apparently natural disasters. If there is system or environment that does not affect properties at all for any given input at any specific time, we will not observe any change at the output or as an observer at the other end and we can say no time passed. I think time is just a reflection of system properties.
Please note that we prefer to avoid using the phrase "natural disaster":

Thank you!
All disasters are human-made. (The term "man-made" is not gender neutral.)
Regarding "What is time?" specifically, Hawking's "A Brief History of Time" still provides excellent background and a useful baseline.
Ilan Kelman Thank you for your valuable input.Thats why i used term apparently "natural disaster"
I read what is time by hawking and no doubt it is very usefull.
i just wanted to share my point of view with others
Time is a moment you want to live. No doubt it will go, but we want to use it as per our our wish. But, time has its own meaning. It will not wait. It will continue passing. Thus, time is a state of mind. No time, it is good or bad. We need to create the 'moment' and make the time pass like the time.
Time is a complex concept that has been studied by philosophers, scientists, and mathematicians throughout history. The concept of time is closely related to the concept of change, as time is often measured by the occurrence of events and the changes that they bring.
Your statement that "time is just a reflection of system properties" is in line with the concept of time as a physical quantity that is closely connected to the properties of the system. In physics, the concept of time is closely related to the concept of space-time, which is a mathematical model that describes the properties of the universe. The properties of space-time are closely related to the properties of matter and energy, and the behavior of these properties can be used to measure the passage of time.
You are correct that the system properties can affect the information that we receive and how we observe the change. For example, if the system is in equilibrium, no change will be observed, and it can be said that no time has passed.
It's also worth mentioning that the concept of time is not the same in all physical theories, and different theories may have different ways of describing time. For example, in classical mechanics, time is an absolute quantity that is independent of the properties of the system, while in quantum mechanics, time is relative to the observer and it's not an absolute quantity.
In summary, time is a complex concept that is closely related to the properties of the system and the changes that occur within it. The concept of time is different in different physical theories, but generally, it's a reflection of the properties of the system.
Muhammad Tahir Time is one of the few things we regard as regular and unchanging. But is it really so constant? We take a look at the physics of time.
Einstein's theory of special relativity revealed that the experience of the flow of time is relative to the observer and their situation. Previously, the work of Isaac Newton had assumed the existence of a "master clock" that kept synchronized time throughout the universe. This clock wasn't really thought to exist, but the concept allowed Newton's equations to work. The key idea was that all observers could agree on the exact same moment of time, according to the Internet Encyclopedia of Philosophy
Chandan Kumar Apparently you want to say time is something spiritual?
Ahmad Al Khraisat thank you for your valuable input.Is it possible that we can consider different defenitions of time?
Dr Mansoor Akhtar thanks for your comments.After reading what you said it looks that there are two possible definitions of time ?Can we assume that time has multiple explanations?
Muhammad Tahir Yes, it is possible to consider different definitions of time. The concept of time is closely related to change and is often measured by the occurrence of events and the changes they bring. In physics, the concept of time is closely related to space-time, which is a mathematical model that describes the properties of the universe. Different physical theories may have different ways of describing time, and time may not always be an absolute quantity. Additionally, the properties of the system can affect how we observe and measure the passage of time.
