CONCAT with NOW()

Hi, not sure if this has been posted before, but I doubt it since I couldn't find it. So here is the problem...
I am performing a SELECT on the CONCAT function on a static string and NOW(). Basically something like

SELECT CONCAT('Time is: ',NOW()) AS 'Time';

this works great on the query browser and mysql commands, but when done through the MySQL Connector (5.1.4) with C++, I get the following :
Log: CALL sp_Test();
Log: STRING IS ??????????????

Now if I do this however:

DECLARE _tmp varchar(20);
SET _tmp = NOW();
SELECT CONCAT('Time is: ',_tmp) AS 'Time';

it returns

Log: CALL sp_Test();
Log: STRING IS Time is: 2008-08-06 11:37:49

which is correct... Is there some special way which CONCAT with NOW is interpreted within the connector as supposed to within MySQL itself?

Thanks
