Hi,
>>Actually I am searching through google to see the each column name description for sys.user$ but not able to find anything useful
These base tables are not documented (public) ... It seems that PTIME column stores the time stamp information when the password's user has changed.
SQL> create user myuser identified by myuser;
User created.
SQL> select
  2    name,
  3    to_char(ctime,'dd/mm/yyyy hh24:mi:ss') ctime,
  4    to_char(ptime,'dd/mm/yyyy hh24:mi:ss') ptime
  5  from
  6    user$
  7  where name='MYUSER';
NAME            CTIME               PTIME
MYUSER          30/04/2008 10:52:25 30/04/2008 10:52:25
-- waiting some time ...
SQL> alter user myuser identified by legatti;
User altered.
SQL> select
  2    name,
  3    to_char(ctime,'dd/mm/yyyy hh24:mi:ss') ctime,
  4    to_char(ptime,'dd/mm/yyyy hh24:mi:ss') ptime
  5  from
  6    user$
  7  where name='MYUSER';

MYUSER          30/04/2008 10:52:25 30/04/2008 10:53:08Cheers
