How to calculate mysql time difference between unix timestamp column and now() format

Calculating the time difference between the following timestamp format mysql column and current time:

Code:

mysql> SELECT created_on FROM `account`;                   
+------------+
| created_on |
+------------+
| 1369986975 |
+------------+
1 row in set (0.00 sec)

Code:

mysql> SELECT TIME_TO_SEC(TIMEDIFF(NOW(), FROM_UNIXTIME(`created_on`))) AS `time_diff` FROM `account`;
+-----------+
| time_diff |
+-----------+
|       799 |
+-----------+
1 row in set (0.00 sec)

This calculates the difference in seconds between current time and unix timestamp column. Obviously, to turn this into minutes or hours:

Code:

mysql> SELECT TIME_TO_SEC(TIMEDIFF(NOW(), FROM_UNIXTIME(`created_on`))) / 60 AS `time_diff` FROM `account`; 
+-----------+
| time_diff |
+-----------+
|   14.0500 |
+-----------+
1 row in set (0.00 sec)

mysql> SELECT TIME_TO_SEC(TIMEDIFF(NOW(), FROM_UNIXTIME(`created_on`))) / 3600 AS `time_diff` FROM `account`;
+-----------+
| time_diff |
+-----------+
|    0.2358 |
+-----------+
1 row in set (0.00 sec)
