Presentation of dates sent over JSON in Single Page Applications
If you really need to send ISO8601 (like you use this representation somewhere), you probably need to create your own, custom solution (no cross-browser formatting method in native JavaScript exists).
There is a JQuery Globalization plugin which will allow you to format dates correctly but I didn't have time to look into it, so I am not sure what is its input.
On the other hand, if you don't have to do anything to dates maybe sending out already formatted dates would be a good idea (it is certainly easier to implement)...
