TIWBSInput and Date type input

[Comograma]

Services run as a different user on Windows which may have different regional settings. I suggest you explicitly specify the date formats when calling date parsing routines to avoid this issue.

Yes, I know. I'd try everything.
Running service as a date format of dd/mm/yyyy and from the client side the date format is yyyy-mm-dd. So the IWBSInput has type bsitDate and the placeholder is yyyy-mm-dd.
When I try to load a date variable to this field, I get the error, because I can't get the date format from client side to be able to call date parsing routines with success.

How can I do it?
Thanks
