Speeltijd: A 12/7 Time System

This clock was developed as an alternative timesystem for the Speelplaats project at Werkplaats Typografie, Arnhem. Speeltime runs 12/7 faster than global time, resulting in weeks with 12 days. Check out the Speelplaats time here

code (javascript)

<script language="javascript">
len=40;
tid = 0;

speeltijd=((1000/12)*7)
clockA = new Array();

var d,x;
days = new Array("Firstday","Secondday","Thirdday","Fourthday","Fifthday","Sixthday","Seventhday","Eighthday","Ninthday","Tenthday","Eleventhday","Twelfthday");

{
  for (i=0;i<num;i++) {
    dt = new Date();

      v1 = Math.round(( dt - timeA[i] )/speeltijd) ;
      if (formatA[i] ==1) {
        sec = v1%60;
