It appears that when events are logged to the audit_event table in audit trail, the event_time is being logged five hours into the future.
I deleted a document at 10:05 am today. After refreshing my query, the document shows in the audit_event table as being deleted 3:05 pm today. The system time on the machine where the repository and audit trail are installed is current. Any ideas what could be causing this? As I write this question, it's 10:30 am, so even if I am looking at the wrong entry (which I don't think is the case, since only 1 entry was deleted today), events are still being logged with future times.
The audit trail tables were created in the same database as the repository that is being audited. Could this be part of the issue?
