As you can see by adding the Zero you just change the time display - not system time as such. Perhaps the next Mac OS will. It also affects only some applications and not all. Calendar stays as it is. For the whole concept & idea take a look at http://longnow.org/ or take a look at my flickr images of the model clock at the Science Museum in Londinium: http://www.flickr.com/photos/hohlwelt/1641884/ Brian Campen also added the link to an interview about the project with Brian Eno.

Update:

I also just got a wonderful gift from LS, Brian Eno's CD "January 07003 | Bell Studies for The Clock of The Long Now." It contains 15 long & short tracks with studies of different bells, from "Deep Glass bells," to "German-style ringing" and "Changes for January 07003, soft bells, Hillis algorithm." I guess all of them are achieved via special software applications that are capable of "physical modelling," creating sounds from simulated "real" physical properties - otherwise the giant "Kolokol" bell woudn't have been able to sound ... The result is beautiful to listen to and meditative as the bell sounds mingle with the background. It has been an utter joy listening to it over the Easter break on a Greek island where the sounds mingled with the continuous local Easter bell ringing, 02007 mixing with 07003.



The CD comes with a little booklet containing two texts "Bells and their history" and "The Long Now Foundation," both interesting texts about the two projects in detail, especially helpful Brian Eno's research into bells.
