One of the most interesting bits of snakeoil explanation I've seen in a while. > This internal clock is a function of the brain that time-sequences sensory information - most notably, perhaps, moving images and sound - so the information can be stored in and retrieved from memory chronologically. Early man's chronological memory allowed him to calculate a predator's location, speed and direction of movement and figure out, on the spot, if it was barreling down on him or not. Timing in memory operation was critical since sensory information had to be retrieved from memory in precisely the same sequence and speed it was stored - otherwise, it would be all jumbled together and wouldn't make sense. ... > Let's say a recording was made of a live performance of Götterdämmerung with the Berliner Philharmoniker on July 21, 1930 between 12 Noon and 5 PM. During the performance the actual time coordinates of what was then Present Time - a unique time coordinate for each instant of the performance - are somehow captured on the recording along with the acoustic information of the musical instruments and singers. When the recording of Götterdämmerung is played at some point in the future - say, one day in 2010 - the stream of time coordinates from July 21, 1930 is projected into the listening room by the speakers along along with the acoustic information. The two out-of-synch streams of time coordinates - the Past Time coordinates from July 21, 1930 and the Present Time coordinates - confuse the listener and reduce his sensory acuity. So, even though the glorious sound of the Berliner Philharmoniker is reproduced in the room the listener cannot hear it in all its glory.
