SOAP plug-in error create Incident Record with HP Service Manager 9.3

I am attempting to create HP SM Change Management tickets via WSDL. The canned flows to add a host and create a workflow succeed (albeit with a some issues/difficulties) but the crux of the issue is as follows.

Populating what the out of the box SM mandatory fields from the vCO flow (leaving the 3 time fields as 'Not set') results in a vCO failure during the 'creating request' stage -- date argument must be a date and non null.

Populating those fields in vCO (which during a test from SoapUI isn't required) does result in the submit to the WSDL proceeding and in fact a response is received, however, the response (the output for the failed create incident request) indicates the data in the date fields are in improper format...

+ parameter name: 'messages.message[0]', value: 'scxmlapi(41) - The data in the 'open.time' field of record " " of file probsummary contains data that does not conform to the SOA datatype in datadict'

The full output/response from the HP SM WSDL is below...

Any thoughts? The HP SM is 9.31 and out of the box config (no customizatinos).
