I'm pretty sure this is something really silly.
Instead of spending another 10 minutes with this ( or better said, while I spend another 10 minutes with this ) I'll ask it here in parallel.
What's wrong with the following statement:
select to_date( '30/10/2009 18:27:35', 'DD/MM/YYY HH24:MI:SS') from dual
The error message is:
Error: ORA-01861: literal does not match format string
SQLState: 22008
ErrorCode: 1861
Position: 0
