Timestamp from MySQL Database

Hi Guys, I'm starting with Datatables and tryied to search the forum but I still can't display a datestamp field using datatables.

I checked the JSON and seems ok:

"date": {"@class": "sql-timestamp","$": "2012-11-23 15:13:50.0"}

At the output I receive just "Object" at timestamp column.

Thanks a lot,

Carlos
