The ISO yyyymmdd date format has been used in US Government weather archive
records since the 1800s when the Hollerith punched card was invented.

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
