Use one of the SQL functions (UNIX_TIMESTAMP()) to pull the date field value out as an integer and do a straight comparison with "%{l}". Or if you write a SQL timestamp string into a date type attribute, it might be smart enough to parse it for you, and then you can do "%{integer:Timestamp-Attr}" and compare with "%{l}".

Not 100% sure the code is there to do that though...
