Hi rgermain,
If you are referring to letting mysql do the date formatting of the fetched data, you can also check out the mysql DATE_FORMAT()function.
It behaves somewhat like the PHP:date() function.
Also, when dealing with DATE_FORMAT() function, you often need to convert the your field into a Unix time, so do check out UNIX_TIMESTAMP as well.
Example from mysql docs:
SELECT DATE_FORMAT('1997-10-04 22:23:00', '%W %M %Y');
-> 'Saturday October 1997'
Cheers.
