Create CRM Event from Creator

Create CRM Event from Creator

I am trying to create a CRM Event from Zoho using the following function:

  1. response = zoho.crm.create("Events", 
  2.                         { "Owner" : "carlgifford",
  3.                          "Subject" : "Test", 
  4.                         "StartDateTime" : "08/01/2012 10:00:00",
  5.                          "EndDateTime" : "08/01/2012 10:30:00", 
  6.                           "WhoID" : input.CRM_ID }, 2);

It does not seem to be working, 

I am thinking that the date formats are incorrect.  How do the dates need to be based?  If I have a Date field in Creator, how do I need to change this (with a formula) to be in the correct format?
