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. 

 Single digits for month and day in a rule or an xml document used to initialize a form will work for only Date control. The Date/Time control requires a valid xml for successful initialization. See Rule Examples for more information.
