Date Time Setting in IIS

We had this strange problem in one of the IIS applications that instead of the regional settings of the IIS server being set to dd/MM/yyyy the IIS application continued to interpret the dates in mm/dd/yyyy format finally we realized that the IIS applications has a provision to set the application pool to be used and these regional setting are selected from what is set on the pool and not the local computer. I am not from the internet applications but yes this is something which is worth knowing.
