I had tested my Web site using the latest versions of Firefox (version 9) and IE (version 9) and had no problems.  When I tried to use IE8 I discovered that it’s JavaScript engine doesn’t know how to parse ISO8601 dates.  Upon further research, I learned that a whole lot of browsers will have issues with the date format I chose.  So much for going with a standard.  So tonight I will add code to do the date parsing rather than relying on the browsers JavaScript engine to do it for me.  I’ll post an update later after I implement the fix for this bug.  Until then I apologize for the error message and the incorrect formatting people are seeing.  If you have IE9 or the latest Firefox then you should be OK.

Update: I added code to parse the ISO8601 date format.  Everything appears tp be working correctly, but I don’t have a lot of different browsers to test with.  My mobile browser (Android) works correctly now.  So this bug should be sufficiently squashed.

Confirmed working in:

• IE9
• IE8
• Firefox 9
• Safari (on iPod)
• Android browser
