We have just installed SQL Server Reporting Services Service 2012(RTM) on SharePoint Server 2010 SP1 according to these instructions http://msdn.microsoft.com/en-us/library/hh231687(SQL.110).aspx
SSRS services are running as a SharePoint service and it works like a charm except;
The problem is SSRS shows the @ExecutionTime and date format as MM/DD/YYYY although it should be DD/MM/YYYY
I have tried some troubleshooting steps;
1) Set regional settings of the Windows Server 2008 R2(SharePoint) to DD/MM/YYYY format.
2) Set the default language of the report to en-GB language.
Unfortunately they didn't work!
Is there any way to change reporting services to DD/MM/YYYY format?
But apparently you tried that already (sorry, was a bit too fast).
