The nature of time

Time, to me, is simply the rate of change of one thing or system of things relative to the rate of change of a reference set of things, that is it nothing else, it is not another 'dimension'. As individuals we slide through time, having no power whatsoever over time past or time future and constantly live through a fine plane of time present, but time present for us is not necessarily time present for the rest of the universe, now we get complicated so I will stop! [thank god! you may say!]
