Iam trying to access reports from other country . Their regional settings of PC are different than English. So when i try to give parameters to my reports it gives me error. What i have found if regional settings are changed Date format automatically change by it self . it does not take any date in English. I have add English language using Internet explorer options. That solves the problem.

But report services should automatically handles this situation. Any idea how would it take the correct date format if it is other than english language.???
