I have some forms that are published on SharePoint that do not have any formatting setup for the date picker fields. When opening the forms in Office 2010 the format would follow the OS format of the computer. So if the OS was formatted as yyyy-mm-dd that is how it would open in the form. With Office 2013 it opens with a format of mm/dd/yyyy no matter how the machine's OS is configured. Does anyone know if there is somewhere in InfoPath or Office to change this behavior. This is happening both on a user's computer running Win7 and my computer running Win10.
