TIME column not visible in PLAN_TABLE output

Question

Hi
I got following output after executing --> SELECT plan_table_output FROM TABLE( DBMS_XPLAN.DISPLAY());
| Id | Operation | Name | Rows | Bytes | Cost |
| 0 | SELECT STATEMENT | | 1 | 7 | 18 |
| 1 | SORT UNIQUE | | 1 | 7 | 18 |
| 2 | VIEW | MTC EXCPN COMPANY V | 1 | 7 | 12 |
| 3 | SORT ORDER BY | | 1 | 91 | 12 |
|* 4 | TABLE ACCESS FULL| MTC_CD_LKUP | 1 | 91 | 6 |
Predicate Information (identified by operation id):
4 - filter ***************
Note: cpu costing is off
I am not getting TIME column as following (below o/p is from a different database):
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 1 | 36 | 6 (17)| 00:00:01 |
| 1 | HASH UNIQUE | | 1 | 36 | 6 (17)| 00:00:01 |
|* 2 | TABLE ACCESS FULL| MTC_CD_LKUP | 1 | 36 | 5 (0)| 00:00:01 |
1) I believe the total of values in TIME column shows total time that will be taken by query. Please correct me if I am wrong.
2) Please tell me how can I get TIME also in first case. Is is because of "cpu costing is off" ?

I hope you are looking for below link:
Oracle included time column in version 10g.
So if you currently run 9i, and use your own SQL scripts to report execution plans (instead of using dbms_xplan.display()) you may want to add a time column to your output. The following pl/sql block is all you need to get going:
