I've always thought of it as 'ignore the scn in the controlfile' not the controlfile is older..

It wasn't the file *name *per se but the *creation time* as in the message
ORA-00279: change 11805815756 generated at *01/30/2008 05:00:15* needed for thread 1
Where we were told that the backups including the controlfile backup were from several hours *before* 5 in the morning. The recovery process seems to know when this change was created - but I don't really see how it can - unless as Andrew suggested the controlfile was actually from *after* 5am. I'm sure I used to know this once, but I'm feeling really old and stupid right now.
