The form designer ensures the XML document used to initialize the form is valid for the XSD schema used to create the form. If the XML document is invalid your form will fail to initialize and will display the message "At least one document URI used to initialize the form is invalid. Please check the document at the URI and check it against any schema. Unexpected namespace http://localhost/ddform.xml: was expecting http://www.frevvo.com/schemas/_F7l4AHnDEeGgieOxgHLpgg"
One example of an invalid XML document is when the XSD contains a repeating element. If minOccurs=3 and the XML document contains only 2 elements then the document is invalid and your form will display the standard error message.

See Time Zones for more information. 
Time data in a form is always converted from the browser's timezone to a valid UTC format when posted in the form XML document in the submissions database. You may see the time in UTC format with a trailing "Z" (UTC) time or the time value plus or minus the UTC offset. Refer to Viewing XML Documents for more information on the Submissions Database and the XML document.
