The datetime design pattern page [1] in the wiki says:

"Any microformat using the date-time-design pattern should use a  
profile of ISO8601. There are currently two widely used profiles which  
should be reused.
- RFC 3339
- W3C Note on Datetimes"

That seems to clear this up, but then there's more confusing language  
on the ISO 8601 page:

"Microformats should use RFC 3339."

In addition to being more specific than the previous recommendation,  
this one applies RFC 2119 "should" to the microformat itself rather  
than implementors of the microformat, which doesn't make much sense.   
Further confusing matters, individual microformats make no mention of  
RFC 3339, referring only to ISO 8601.  We should probably clarify the  
actual source(s) for date formats before we spend too much time  
testing them.
