We wanted to change the date format as per user inputs from the application. For example, if the user selects the date and time format as dd/mm/yyyy hh:mm:ss then it should reflect the same in SSRS report, or if user selects date time format as mm/dd/yy h:mm:ss then it should reflect accordingly in SSRS report. But, as per inputs from MS support team, there is no such functionality available as of now from SSRS end. I believe this should be added to SSRS as it would provide flexibility to users and add more value to the SSRS reports.
