Personally I agree that people really should use UTC, but bear in mind that many other users will disagree with this and want their system to use local time for everything.. especially when using an auditing framework like Envers, as auditing is often more related to business and legal requirements than to superior technical solutions. (After all timezones are a non-scientific, political matter...)

My solution in similar cases was to actually mandate all servers we'd deploy to use UTC as a system wide setting... simplifies and avoids other issues as well. Wouldn't you agree that is the better solution?
