@pagan,
Like others have said your getting into a semantics debate. Time is just a word we use to describe a tool that helps us understand and measure the behavior of atoms and other things. Recently I have been using time to measure how long it takes for my wife to come home, unwind, get undressed, and cozy up. In a way I can measure the length just as you can place two apples together and count them. We can argue the semantics all day but I think until you can find a better tool, a better word, or a better way to describe how long it takes for your wife to get pregnant and deliver a baby, then the argument isn't going to help anything.
Time is relative just like you don't use a hammer to screw two pieces of metal together. We use a hammer to nail two boards together. Now we have power tools that replaces the hammer. Now we just change the word to "nail gun". The nail gun is the more efficient tool to use for the job. Just as a second is the most efficient tool to use in measuring how many kilowatts of electric energy my house is pulling from the grid. The hammer is relative to the job being done. The time is relative to job needing measured. We never needed Einstein to figure that out, it's common sense!
What the question really is, is this: Can we fathom eternity, can we fathom finiteness or "nothingness"? If we can fully fathom these things then time would be completely irrelevant. Time would still exist, the word, the meaning(semantics), and the usage of the word would still be relevant; but we would need a new tool, a new word, and a new reason for understanding and measuring infinity. Until then, a wise person should keep measuring their time.
