SSRS Date Parameter Foreign Language issue

I have a client in Germany using an SSRS report and the date parameter is showing "OKT" instead we need it to be "OCT" for october...... is there a setting on his locale machine to make sure GETDATE() is already converted or will a convert function work???

Is the report parameter defined as a date - or a string? If defined as a date - then there shouldn't be any issues with what you are 'seeing' in SQL Server as SSRS will pass the date selected correctly.

i did just notice that it was a text! I am going to try and make it date/time type and hopefully that will fix it!!
