I believe the yyyy-mm-dd format is also known as 'international' date
format.  For my purposes it has the very nice effect of a text sort
producing date sorted material. 

I don't know of any regional convention that uses the yyyy-dd-mm format
with the '-' separator, I believe that it is customary in the vast
majority of locales to use '/' or '.'.  Perhaps someone more travelled can
provide some perspective.

Does anyone know of an iso standard that attempts to enumerate these?  All
Microsoft and many other applications treat mm/dd/yyyy as being the 'US'
format however I always switch it to the above format for consistency.
