So I was using the php function php_decode to convert a JSON encoded data result from a web service (More on that later)  But it was choking on the JSON formated data result.  Why?  well, the C# library that I was using to generate the JSON data encoded a DateTime object as 

            ”TimePosted”: new Date(1221571632000),

javascript picks up on the new Date function, but not PHP.  so I had to switch the JSON data result to return the date as a string

            ”TimePosted”: “9/16/2008 1:27:12 PM”,

The website that I found in the process of finding this out might be helpful for someone else too. http://www.jsonlint.com/  a JSON validator.  and it takes JSON data and make it easy to read too, that a big bonus!

That’s it.  JSON on!
