We are using SQL 2012 Reporting Services in Integrated mode with SharePoint 2010.
Displaying reports using the Report Viewer webpart displays date parameters in US Date format.
Contrary to this thread we have found that the Browser language and Operating system language settings have no effect on the date displayed in the parameter box.
Adding UICulture="en-AU" to <PAGE> tag in the "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\ReportServer\RSViewerPage.aspx" only helps if you actually click directly on reports in report libraries - but is a bad choice for future upgrades / Service Packs etc.
Has anyone got a real fix for this?
