I don’t think that Oracle is sensitive to the timestamp of datafiles. Even RMAN’s SET UNTIL clause uses an SCN to TIMESTAMP match on the database server.

Yep - the filer has the wrong date and timezone offset after the maintenance.  

So, now I'm wondering about the impact to a running database when the timestamp on the datafiles jump ahead when they correct the time on the netapp filer. Since the netapp filer is "behind" I'm thinking this will be okay. But if the netapp filer had been ahead, I can imagine this would be a problem if we had to adjust the date backward in time.

Haven’t actually seen anything like that, but I’d check the time on the filer.

We have a Solaris 10 server and I just noticed that the dates on newly created files aren't matching the SYSTEM date of the server. The filesystem in question is mounted on a Netapp device and the netapp device was taken down for maintenance (controller upgrade) this past weekend.  

Has anyone seen this behavior before - I've sent an email to the SA but thought I'd ping the list to get some input. (Perhaps I'm just sleepy and am overlooking something obvious):

Am I missing something, or could this be a problem?
