Hi, This sounds like a bug. The problematic date seems to coincide with the switch to daylight saving time in Europe, so my guess would be that it's somehow related to that. It would be great if you could file a bug report at https://issues.apache.org/jira/browse/DERBY so that we can track the problem. Thanks, -- Knut Anders
