Message from Ian Galpin re ISO 8601 web pages

One change is that I have tidied up the document slightly and archived a copy of it at:

Chris Newman has authored a completely new document, which has since undergone several revisions. The current version '05' can be found at: This site contains all previous revisions; and it is worth checking to see if a version '06' appears at some future time.

If you want to add a few extra links then there are now plenty more to choose from.

Here are a few others that you may find useful:
