This is a question that originated from this question by Jamie.

I thought I'll check Dougman's answer. What's happening here? A restore?

select created from dba_users where username = 'SYS';

select min(created) FROM dba_objects;

select created from v$database;

CREATED                   
------------------------- 
10-SEP-08 11:24:44        

MIN(CREATED)              
------------------------- 
10-SEP-08 11:24:28        

CREATED                   
------------------------- 
18-DEC-09 15:49:00      

Created from v$database is more than one year later than creation date of user SYS and SYS' objects.
