mySQL把秒转换成日期

mysql>  SELECT  SEC_TO_TIME (3600);
+ --------------------+
| SEC_TO_TIME (3600) |
+ --------------------+
| 01:00:00           |
+ --------------------+
1 row  in  set  (0.00 sec)

mysql>  SELECT  TIME_TO_SEC( '00:01:00' ) A;
+ ----+
| A  |
+ ----+
| 60 |
+ ----+
1 row  in  set  (0.00 sec)


如：
SELECT SEC_TO_TIME(sum(time_len_s)) FROM `cti_agent_login`;
