You could use the LIMIT command, like this:
SELECT ER_RL_GE_LOG.ID_GE, ER_RL_GE_LOG.LOGIN_DATE, ER_RL_GE_LOG.LOGIN_TIME 
FROM ER_RL_GE_LOG 
ORDER BY ER_RL_GE_LOG.LOGIN_DATE DESC , ER_RL_GE_LOG.LOGIN_TIME DESC LIMIT 1,1;

Sorry stathisx, you are right -- LIMIT is only supported in MySQL.

For SQL, the closest alternative is TOP like you have, so you need to use 2 steps to get ONLY the second record.
I.E get the top 1 of the top 2 sorted the other way. Something like this:
SELECT TOP 1 * 
FROM (SELECT TOP 2 ER_RL_GE_LOG.ID_GE, ER_RL_GE_LOG.LOGIN_DATE, ER_RL_GE_LOG.LOGIN_TIME FROM ER_RL_GE_LOG ORDER BY ER_RL_GE_LOG.LOGIN_DATE, ER_RL_GE_LOG.LOGIN_TIME DESC) ORDER BY ER_RL_GE_LOG.LOGIN_DATE, ER_RL_GE_LOG.LOGIN_TIME ASC;
