''TIME'' - definitions
==
Can ''Time'' exist without matter ?
No.
Therefore, the right definition of ''time'' is to say: ''Gravity-time''
We have Earth ''gravity-time''.
Another planets have their own ''gravity-time''
From ''gravity-time'' is possible to create another definitions of ''time''
( atomic time-clock , biological-time, local-time, psychological-time . . . . )

Anything that has a beginning and an ending has 'time' between those two points. Divided into 10 parts makes visualizations easier to construct.

Agree,
''Time'' is artificial / mathematical measurement between a beginning and an ending.
''Time'' doesn't have ''nature''.
''Time'' is not a ''nature''.

Proper time
https://en.wikipedia.org/wiki/Proper_time
------
It means, SRT plays with two kinds of time:
1- ''proper time'' --- ''independent of coordinates''
In terms of Minkowski four-dimensional spacetime,
''proper time'' is Constant on the World line
2 - ''proper time interval'' between two events
on the Word line is the changes in the ''proper time''.
This ''proper time interval'' is Relative property
