You can call time an unfolding of events... but what if there were no events as in a pure emptyness without objects... or objects present yet never changing in any way? Then there could still be time because you might have a consciousness that was watching the nothingness. That mind might be thinking "well nothing has happened and here I am watching it." here you have an unfolding of events in that mind so time would exist-or what if it was not thinking anything along with no objects or objects changing? Would there be time then-or even awareness? I mean absolutely no thought at all. So maybe all it takes for time is self awareness. Like the 120v outlet that has nothing plugged in-the potential is there but nothing is being done. But what about the awareness of a rabbit that is aware of pleasure and pain? Is there time because things are changing in the consciousness of the rabbit even if there is no mind to register it? Maybe a pure awareness has no time because nothing ever changes-no movement or changes in that consciousness or any observed objects. Maybe this unchanging awareness said "well crap this is getting old I think I'll create something". But could it even say that because at the moment it had a thought that would be like the beginning and at the beginning there could be no boredom because there was no awareness of any past events. Does the answer lie in the word self? It seems to be resolving to where there is no time as an independent entity but that there is only the progression of events. As soon as you have an observer Bingo! Does a dog know time? It certainly has a memory as in what time the kids get home from school and a chance to play. Maybe it takes an intelligent mind to know time. I don't know! Time for another beer.
