Version 7 is millis since the Unix epoch in version 7. There is some back and forth on this when the PR was initially created. So while it may be confusing to use epochMillis and have timestamp throw UOE, it would be a hazard to do otherwise. ------------- PR Comment: https://git.openjdk.org/jdk/pull/25303#issuecomment-3352327672
