Answer 1

Use the Date_format function of mysql.

"SELECT DATE_FORMAT(`hour`, '%Y-%m-%d %H:%i') AS `time` FROM `dataTable`"

Explanation:

The STR_TO_DATE function always return the date in the format of 2008-09-15 22:23:00

SELECT STR_TO_DATE('Monday 15th September 2008 22:23:00', '%W %D %M %Y %H:%i:%s');
+----------------------------------------------------------------------------+
| STR_TO_DATE('Monday 15th September 2008 22:23:00', '%W %D %M %Y %H:%i:%s') |
+----------------------------------------------------------------------------+
| 2008-09-15 22:23:00                                                        | 
+----------------------------------------------------------------------------+
1 row in set (0.00 sec)

Check the above example: the second parameter in STR_TO_DATE function is the format of the parameter 1 to tell the function that in which format parameter 1 is passed in the function.
