Check actual apply log time on standby database after synchronization

Question

Hi All,
I want to check the date and time stamp of applied archived logs on stanby database. How should I check that??
My dataguard link was broken for sometime and meanwhile lot of transactions happened on primary database. Now When the link came up the synchronisation happened within few hours and ultimatly transport and appliy lag became 0. But now I want to check actual time taken for tranporting the logs and applying them on standby database. Is there any way I could do that easily..
Thanks

This script written by Yousef Rifai I found here http://www.dba-village.com/village/dvp_forum.OpenThread?ThreadIdA=34772&DestinationA=RSS might be just what you need (run on standby database):
set ver off
alter session set nls_date_format='dd-mon-yy hh24:mi:ss'
select app_thread, seq_app, tm_applied,
nvl(seq_rcvd,seq_app) seq_rcvd, nvl(tm_rcvd,tm_applied) tm_rcvd
from
(select sequence# seq_app, FIRST_TIME tm_applied, thread# app_thread
from v$archived_log where applied = 'YES'
and (first_time, thread#) in (
select max(FIRST_TIME ), thread#
from v$archived_log where applied = 'YES'
group by thread# )
(select sequence# seq_rcvd, FIRST_TIME tm_rcvd, thread# rcvd_thread
from v$archived_log where applied = 'NO'
and (first_time, thread#) in (
select max(FIRST_TIME ), thread#
from v$archived_log where applied = 'NO'
group by thread# )
where rcvd_thread(+)= app_thread
