How to change the format of infotable column (without datashape) bound to Grid

Hi,

I have service that returns generic infotable column 1 column is the Date time which will stay always, the other column change.

The logic is working perfect, all I have left to do is to format the dateTime column to a token (depends on the user's language).

I tried to do it on the server side in the service - it is not working.

On the client side in the mashup I cant really do it for infotable without datashape.

Any ideas?
