Get the last login date for all users in Oracle 11g

We have Oracle 11g so the following query didn’t work.

select USERNAME,LAST_LOGIN from dba_users

Then I searched and people suggested multiple ways and i got confused. What is the correct way to get the last login date for all users in oracle 11g?

select username, logon_time
from v$session

or

SELECT
    username,
    timestamp
FROM
    sys.dba_audit_session

or

select username, timestamp
from dba_audit_Trail 

Answer

DBA_AUDIT_TRAIL table records all the actions performed by the user based on level of auditing enforced and it also records login and logoff time of every user which can be identified from action column.

 SELECT  MAX(TIMESTAMP), A.USERNAME FROM DBA_AUDIT_TRAIL A WHERE ACTION_NAME = 'LOGON'
    GROUP BY USERNAME ORDER BY 1 DESC;
