You can join to v$statname to turn 13 into 'session connect time'. If you are using 7.0 - 7.2 and want to turn this into the wall clock time that a session logged in you can use:
select s.sid, s.username,
to_char((sysdate-(hsecs - value )/(100*60*60*24)),'dd-mon-yy hh:mi:ss') cnt
from v$sesstat sess, v$session s, v$timer where statistic# = 13
and s.sid = sess.sid
Providing you have resource_limit/timed statistics = true. This only works before Oracle 7.3. From Oracle 7.3 onwards see V$SESSION.LOGON_TIME .
This particular statistic returns:
A number representing the time when the session connected to the server. Pre 7.3: The unit of measure is in 1/100'ths of a second and is the same as the value of V$TIMER at the time the session connected.
7.3 onwards: The unit of measure is now seconds. The time is a number of seconds since some epoch so can no longer be related to V$TIMER.
