The order yyyymmdd is used a lot with various separators in computers and digital media files as alphabetic sorting rules sort into data order.

In ISO8601, the only allowable separator in date format is a hyphen, or no separator, so, at best, they are using "mutant ISO8601."

On Sunday, a Fox News Channel clip from Prague television showed the date format of the clip as (yyyy.mm.dd) i.e. 2009.04.05

Isn't it interesting that others are moving to the ISO standard date format?

Dear John and Stan,

I suspect that dates in the ISO 8601 format are gradually becoming more popular as soon as people realise how useful they are in any computer environment.

As an example, I store drafts of the Metrication matters newsletter (like this one for this month) as: mm-newsletter-2009-04

I don't need to have the day on the end because the Metrication matters newsletter is sent on the 10th day of each month.

The ISO 8601 format means that I can sort all of the back copies in date order by sorting any list either alphabetically or by date simply and easily. You can see the full list of the old Metrication matters newsletters — in date order — at the bottom of http://www.MetricationMatters.com/newsletter.html

Cheers,
