Microformat datetime design pattern is different from what is being parsed

[GoogleCodeExporter]

What steps will reproduce the problem?
1. the datetime design pattern has dashes in the date
http://microformats.org/wiki/datetime-design-pattern 
2. Running js-hcalendar on a page that has the dtstart in the above format
fails to work properly

What is the expected output? What do you see instead?
js-hcalendar is unable to find the dtstart for the event.

What version of the product are you using? On what operating system?
Rel. 2007-Feb-01 running on FF2 & IE7 for WinXP

Please provide any additional information below.
I modified a line in parseDT(dt) to the following.
var result = dtText.match( /^(\d{4})-(\d{2})-(\d{2})/ );

Thanks for the report.  Can you attach your proposed patch as a diff (say, with 
"svn
diff")?
