current_timestamp and sysdate are diffrent.

Hi,

I am facing a problem of having difference in sysdate and current_timestamp. Server date matches with sysdate but not with current_timestamp.

$ sqlplus / as sysdba

SYSDATE returns the date and time that belongs to the host where the database is sitting as reported by the Operating System.

On the other hand, CURRENT_TIMESTAMP depends on the session.

PAVB,

Thanks for reply. But this fact is known to me. I have already check the OS date and not changed current timestamp. Still facing same problem.

Are you in the same timezone as the database server? Because it could be that CURRENT_TIMESTAMP is specific to the time on the client machine, rather than the server. Just a thought...

It is the other way around, SYSDATE depends on the server while CURRENT_TIMESTAMP depends on the session a.k.a. the client session.
