What is the “right” JSON date format?

Question

I\'ve seen so many different standards for the JSON date format:

\"\\\"\\\\/Date(1335205592410)\\\\/\\\"\"         .NET JavaScriptSerializer
\"\\\"\\\\/Date(         


        

Answer 1

From RFC 7493 (The I-JSON Message Format ):

I-JSON stands for either Internet JSON or Interoperable JSON, depending on who you ask.

Protocols often contain data items that are designed to contain timestamps or time durations. It is RECOMMENDED that all such data items be expressed as string values in ISO 8601 format, as specified in RFC 3339, with the additional restrictions that uppercase rather than lowercase letters be used, that the timezone be included not defaulted, and that optional trailing seconds be included even when their value is "00". It is also RECOMMENDED that all data items containing time durations conform to the "duration" production in Appendix A of RFC 3339, with the same additional restrictions.
