Barbour is right saying universe is timeless and wrong saying that there is no time.
Time is run of clocks in timeless universe.

Yours Sincerely Amrit Sorli

i am using the worst computer i have ever seen in my life so cant right now so have written down the address.

i think that the best quote is einstien when he wrote that time is an illusion however present. i think that even then he saw that there were many dimensions to time.we ieperience it in a linear way but it can be bent or changed.
unless,of course he was speaking in a quantum physic vein in which case he was absolutely right as nothig unwittnessed exists.go to www.platonia.com it is julian barbours web page.

I am plagued by the persistent notion that my sensory organs and the three and one half pounds of fatty grey matter they are connected to are not adequate tools for making conclusive observations of the universe, a thing that appears to be as far beyond me as I am beyond a speck of dust. Nevertheless I am equally hounded by a burning desire to do exactly that. Intuition and imagination are all I have that allow me to see beyond this biologically generated realm of smoke and mirrors. I envision a universe that is unbound by the human concepts of dimension and duration. I believe these are merely the most basic evolutionary developments needed for locating and securing the things needed for survival. A sense of three spatial dimensions allows one to establish the general location of food or other necessities. A partial sense of an additional dimension, time, pinpoints their exact position. A helpful analogy would be to imagine spatial perception as an ability to recognize a particular highway that leads to food. Temporal perception marks the precise milepost location of the restaurant. I must partially disagree with the late Douglas Adams. While time is an illusion, lunchtime is most certainly not.
