Show Time of signature in the Date binding (Document Extracting)

Is there any way to get the full date and time (with timezone) in the date field (Via document Extracting)? It shows up in the actual signature block, but we need to show it in a separate line as well and the time of signing is critical. So far we've tried : [sig1.fullname1.label1.{approval.signed}] [sig1.fullname1.label1.Date1] both with and without setting the adobe form field format category to Date with format "m/d/yyyy h:MM tt" but no matter what all we get is the date in "mmmm d, yyyy" format thanks, Dan
