Thanks. We'll keep that in mind as a future project because it may cause a lot of changes in code, but I don't think it's the main cause here because we set all the environment in one place and every form, class, etc. use the same setting. So, SET CENTURY and SET DATE (for example) are only set once and never touched afterward.
