Does anyone know how this happens?
Thanks, we confirmed - looks like any "Last Week" search can show Wednesday instead of Monday there. The tooltip and the data are correct, so it's just cosmetic. Good find. We filed a bug to fix in an upcoming release.
This is new to me - there must be something in the data throwing it off, or something not collated. I'll check with the team.
Edit - what is the timeframe you're searching where you see this so I can be sure we're reproducing it correctly?
It's a UserLogonFailure for a specific user, with Last Week in the time dropbox. It's like the record was written with the actual-time correct but the timestamp is wrong...
UPDATE: This happens for any user specified for that timespan for UserLogonFailure.
Good to know, thanks Nicole.
