<!-- THREE STEPS TO INSTALL ISO CLOCK:
1. Copy the coding into the HEAD of your HTML document
2. Add the onLoad event handler into the BODY tag
3. Put the last coding into the BODY of your HTML document

This JavaScript code is deprecated since it is still using the getYear() method of date that Microsoft Internet
Explorer badly implemented in search for a Y2K bug. Any
modern implementation should be using getFullYear() method
instead that Microsoft Internet Explorer implemented
correctly.
