What is the proper DateTime Format for WebHook JSON Return Fields?

[Anonymous]

Simple, I'm looking through the documentation and haven't seen much of any reference.

I have a webhook that is looking to provide a lastActivityDate in the JSON response, which will then be assigned by to a field on the contact in Marketo. 

I've pieced together this format:
MM/dd/yyyy,HH:mm

Based on some document I found that had references to an HTML Date field being posted, but that is about it.

Could someone confirm the format in relative short order?

Hi Ryan,
 it should behave the same as forms. The datetim format would be MM/dd/yyyy,HH:mm

For example today at 3 pm would be

06/27/2012,15:00
