Then try this: absolute time is the rate at wich fundamental particals vibrate on their spin axis,( ie nutation). So, if as mentioned above, the quantal state is defined by a set of 4 numbers, one being nutation, then time is just one dimention of matter.
Now if you consider this to be simple, consider that quantum "spin" is not the axial spin of common definition. Quantum spin is... er, ah, well I don't know what in hell it is.
Lets say that absolute time proceeds a some even multiple of Plank time, but you will still need a clock to measure it....WHAT is the clock measuring? I don't believe I know and to be fair I don't think ANYBODY can explain it. But we can keep trying.
