Things change and we have had to invent the concept of time to start to measure how we experience change.
It may be a mistake to view time as other than a human measuring stick.
We experience all types of change and then build an invented framework to try to understand, measure or control the perceived changes.
Part of one of these frameworks revolves around the concept of time as a means of measuring perceived duration or rate of change
At a basic level the change of the revolving earth and of night and day warranted the invention of the 24 hour clock, hours and minutes.
As we became more sophisticated we invented calendars to measure longer periods of change.
We then invented clocks to measure smaller periods of change.
We then invented atomic clocks to measure ever smaller periods of change.
It is important to separate the 'real or actual' changes that are occuring from the intellectual but invented 'measuring stick'.
It maybe that there is endless multivariate changes occuring and we may be trapping ourselves with our invented 'measuring sticks of which time is one.
