Yes, perhaps if one lived on Saturn, you might use those rotations, why not? And, I did give the correct answer. My question is why you and others do not think so. Perhaps you folks should define what you all mean by time since I have done that precisely. So, this is not about me, it is about bout you all.
Now, using only astronomical observations I can convert between the 2 times.
So, this is not relative but absolute.
You see, what is up and down? What is north and south? One chooses some time standard such as the earth's motion to define time. Of course, Einstein claimed time varies based on motion and gravity, but that only means that clock deviated from the defined standard. Both observers stills agree on the earth's position, hence they must also agree upon the standard time definition. We have no choice but to conclude if clocks deviate from the standard, they did not live different times, some clock is wrong compared to the standard that all parties agree upon..
Chinglu, Thanks again for above the reply.
I note your Yes, perhaps if one lived on Saturn, you might use those rotations, why not?
So we would have a different time reality on Saturn.
I do have more to say about this, but will leave it in abeyance at the moment. I really need first, to see your specific response to RW's post #759 - that's really important for my understanding. I know you probably think you have answered it somewhere in the above several posts, but it's not clear to me, and my mind in these things is quite simple, so please, it won't take you much to click onto that post (#759) and provide a direct answer to RW, as also, I do not want to be seen to be arguing his point. Thanks.
