''TIME'' - definitions
Can ''Time'' exist without matter ?
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 . . . . )

Gravity is curved spacetime so time is one half of gravity. The other half is space. Space keeps everything from happening in the same place and time keeps everything from happening at once. I don’t know of any better definition for space and time.

Can Time exist? No. In my opinion, it is merely a concept....albeit a useful concept. Time, love, the Easter Bunny are all useful concepts that do not, in and of themselves, exist. There is no "river of time" except in our imaginations. There is only the Universal Now.

Experiments that attempt to show "time" effecting matter in some way all come back to the same problem....the timepieces. Because clocks (even atomic clocks) CAN be effected by outside influences (like gravity) but time itself can not. Concepts do not respond to gravity. There is no universal timepiece ticking away somewhere in the universe. There is only different concepts of "time". And concepts don't effect matter.

Just so!
It's a way to describe change. All measures of time are a function of matter and its rate of change.
